特定線量下業務に従事する労働者の放射線障害防止のためのガイドライン Guidelines on Prevention of Radiation Hazards for Workers Engaged in Work under a Dose Rate Lower than Designated Dose Rate 平成二十四年六月十五日付け基発六一五第六号 Labour Standards Bureau Notification No. 0615-6 of June 15, 2012 平成二十六年十一月十八日付け基発一一一八第六号 Labour Standards Bureau Notification No. 1118-6 of November 18, 2014 特定線量下業務に従事する労働者の放射線障害防止のためのガイドライン Guidelines on Prevention of Radiation Hazards for Workers Engaged in Work under a Dose Rate Lower than the Designated Dose Rate 制定：平成二十四年六月十五日付け基発六百十五第六号 Enactment: Labour Standards Bureau Notification No. 0615-6 of June 15, 2012 改正：平成二十五年十二月二十六日付け基発千二百二十六第二十一号 Amendment: Labour Standards Bureau Notification No. 1226-21 of December 26, 2013 改正：平成二十六年十一月十八日付け基発千百十八第六号 Amendment: Labour Standards Bureau Notification No. 1118-6 of November 18, 2014 （下線部分は平成二十六年十一月十八日付け基発千百十八第六号による改正部分） (The underlined contents herein are the amended parts by Labour Standards Bureau Notification No. 1118-6 of November 18, 2014) 第一趣旨 Section 1 Objectives 平成二十三年三月十一日に発生した東日本大震災に伴う東京電力福島第一原子力発電所の事故により放出された放射性物質に汚染された土壌等の除染等の業務又は廃棄物収集等業務に従事する労働者の放射線障害防止については、「東日本大震災により生じた放射性物質により汚染された土壌等を除染するための業務等に係る電離放射線障害防止規則」（平成二十三年厚生労働省令第百五十二号。以下「除染電離則」という。）を平成二十三年十二月二十二日に公布し、平成二十四年一月一日より施行するとともに、「除染等業務に従事する労働者の放射線障害防止のためのガイドライン」（平成二十三年十二月二十二日付け基発第千二百二十二第六号。以下「除染等業務ガイドライン」という。）を定めたところである。 The "Regulation on Prevention of Ionizing Radiation Hazards at Works to Decontaminate Soil and Waste Contaminated by Radioactive Materials Resulting from the Great East Japan Earthquake and Related Works" (Order of the Ministry of Health, Labour and Welfare No. 152 of 2011; hereinafter referred to as the "Ionizing Radiation Regulation for Decontamination") was promulgated on December 22, 2011 and came into effect on January 1, 2012 for the prevention of radiation hazards to workers engaging in the works of decontamination, etc. of soil and waste or works for collecting wastes, etc. contaminated by radioactive materials generated by the accident at the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company caused by the Great East Japan Earthquake on March 11, 2011. In addition, the "Guidelines on Prevention of Radiation Hazards for Workers Engaged in Decontamination Works" (Labour Standards Bureau Notification No. 1222-6 of December 22, 2011; hereinafter referred to as the "Guidelines on Decontamination Works") were established together with the promulgation of the Regulation. 今般、避難区域の線引きの変更に伴い、「平成二十三年三月十一日に発生した東北地方太平洋沖地震に伴う原子力発電所の事故により放出された放射性物質による環境の汚染への対処に関する特別措置法」（平成二十三年法律第百十号。以下「汚染対処特措法」という。）第二十五条第１項に規定する除染特別地域又は同法第三十二条第一項に規定する汚染状況重点調査地域（以下「除染特別地域等」という。）において、生活基盤の復旧、製造業等の事業、病院・福祉施設等の事業、営農・営林、廃棄物の中間処理、保守修繕、運送業務等が順次開始される見込みとなっており、これら業務に従事する労働者の放射線障害防止対策が必要となっている。 In association with the recent redefinition of the demarcation of evacuation areas, local infrastructure restoration work, manufacturing and other businesses, operations of hospitals, welfare facilities, etc., agriculture and forestry activities, intermediate processing of waste, maintenance and repair work, transportation services, etc. are expected to begin in sequence in the special decontamination areas provided for in Article 25, paragraph (1) of the "Act on Special Measures Concerning the Handling of Environmental Pollution by Radioactive Materials Discharged by the Nuclear Power Station Accident Associated with the Tohoku District Off the Pacific Ocean Earthquake That Occurred on March 11, 2011" (Act No. 110 of 2011; hereinafter referred to as the "Act on Special Measures Concerning the Handling of Radioactive Pollution") or in the intensive contamination survey areas provided for in Article 32, paragraph (1) of the same Act (hereinafter referred to as "special decontamination areas, etc."). Under this circumstance, it is necessary to take measures to prevent radiation hazards to workers engaging in these works. この点に関し、改正前の除染電離則の適用を受ける事業者は、除染特別地域等において、「土壌等の除染等の業務又は廃棄物収集等業務を行う事業の事業者」と定められており、それ以外の復旧・復興作業を行う事業者は、除染電離則の適用がなかったため、これら復旧・復興作業の作業形態に応じ、適切に労働者の放射線による健康障害を防止するための措置を規定するため、除染電離則の一部を改正し、平成二十四年七月一日より施行することとしている。 In this regard, employers subjected to the application of the Ionizing Radiation Regulation for Decontamination before amendment were defined as "employers who engage in the works of decontamination of soil, etc. or works for collecting wastes" in special decontamination areas, etc., but other employers engaging in restoration and reconstruction works were excluded from the application of the Ionizing Radiation Regulation for Decontamination. For this reason, the Ionizing Radiation Regulation for Decontamination was partially amended to prescribe measures to appropriately protect workers from health hazards caused by radiation according to the types of restoration and reconstruction works, and will come into effect as of July 1, 2012. このガイドラインは、改正除染電離則と相まって、復旧・復興作業における放射線障害防止のより一層的確な推進を図るため、改正除染電離則に規定された事項のほか、事業者が実施する事項及び従来の労働安全衛生法（昭和四十七年法律第五十七号）及び関係法令において規定されている事項のうち、重要なものを一体的に示すことを目的とするものである。 The purpose of these Guidelines is to comprehensively present matters provided for in the amended Ionizing Radiation Regulation for Decontamination, as well as the matters an employer is obligated to perform and important matters among those provided for in the Industrial Safety and Health Act (Act No. 57 of 1972) and relevant laws and orders, in order to prevent radiation hazards more appropriately in restoration and reconstruction works in combination with the amended Ionizing Radiation Regulation for Decontamination. なお、このガイドラインは、労働者の放射線障害防止を目的とするものであるが、同時に、自営業、個人事業者、ボランティア等に対しても活用できることを意図している。 These Guidelines aim not only to prevent radiation hazards to workers, needless to say, but also to be available to self-employed workers, sole proprietors, volunteers, etc. 事業者は、本ガイドラインに記載された事項を的確に実施することに加え、より現場の実態に即した放射線障害防止対策を講ずるよう努めるものとする。 An employer is to endeavor to appropriately implement the matters described in these Guidelines and take measures fit for the situations of actual work sites to prevent radiation hazards. 第二　適用等 Section 2 Application このガイドラインは、汚染対処特措法に規定する除染特別地域等において、原発事故により放出された放射性物質（電離放射線障害防止規則（昭和四十七年労働省令第四十一号。以下「電離則」という。）第二条第二項の放射性物質に限る。以下「事故由来放射性物質」という。）により平均空間線量率が二・五マイクロシーベルト毎時を超える場所で行う除染等業務以外の業務（以下「特定線量下業務」という。）を行う事業の事業者（以下「特定線量事業者」という。）を対象とすること。適用に当たっては、次に掲げる事項に留意すること。 These Guidelines apply to employers who engage in an operation other than operations for decontamination, etc. in places where the average air dose rate exceeds 2.5 μSv/h due to radioactive materials released from the accident of the nuclear power plant (limited to radioactive materials provided for in Article 2, paragraph (2) of the Regulation on Prevention of Ionizing Radiation Hazards (of the Ministry of Labour Order No. 41 of 1972; hereinafter referred to as the "Ionizing Radiation Regulation"); hereinafter referred to as "accident-derived radioactive materials") (hereinafter referred to as "work at the designated dose rate") in the special decontamination areas, etc. provided for in the Act on Special Measures Concerning the Handling of Radioactive Pollution (hereinafter referred to as "employers engaging in business at designated dose rate"). The matters described below are considered when applying these Guidelines. なお、東電福島第一原発の周辺海域での潜水作業等はこのガイドラインの対象とはしないが、潜水作業等を行う事業者は、潜水作業等の従事者に対し、外部被ばく線量の測定及びその結果の記録等の措置を実施すること。 Underwater works, etc. in the sea areas close to the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company are not included in the scope of application of these Guidelines. An employer who engages in underwater works, etc., however, takes measures, such as measurement of external exposure doses and recording of the results, for workers engaging in underwater works, etc. （一）　「除染等業務」とは、土壌等の除染等の業務、廃棄物収集等業務又は特定汚染土壌等取扱業務をいうこと。除染等業務を行う場合は、除染電離則の関係規定及び除染等業務ガイドラインが適用されること。 (1) "Decontamination and Related Works" means works of decontamination of soil, etc., works for collecting wastes., etc. or works for handling designated contaminated soil and waste When performing decontamination and related works, the relevant provisions of the Ionizing Radiation Regulation for Decontamination and the Guidelines on Prevention of Radiation Hazards for Workers Engaged in Decontamination Works apply. （二）　「特定線量下業務」についての留意事項 (2) Considerations for "work at designated dose rate" イ　製造業等屋内作業については、屋内作業場所の平均空間線量率が二・五マイクロシーベルト毎時以下の場合は、屋外の平均空間線量が二・五マイクロシーベルト毎時を超えていても特定線量下業務には該当しないこと。 (a) Indoor work, such as manufacturing, does not fall under work at the designated dose rate when the average air dose rate in the place of indoor work is 2.5 μSv/h or below even if the outdoor average air dose exceeds 2.5 μSv/h. ロ　自動車運転作業及びそれに付帯する荷役作業等については、①荷の搬出又は搬入先（生活基盤の復旧作業に付随するものを除く。）が平均空間線量率二・五マイクロシーベルト毎時を超える場所にあり、二・五マイクロシーベルト毎時を超える場所に一月あたり四十時間以上滞在することが見込まれる作業に従事する場合、又は②二・五マイクロシーベルト毎時を超える場所における生活基盤の復旧作業に付随する荷（建設機械、建設資材、土壌、砂利等）の運搬の作業に従事する場合に限り、特定線量下業務に該当するものとすること。 (b) Driving vehicles and incidental load handling work, etc. are to fall underwork at the designated dose rate only when (1) the unloading or loading site (excluding operations associated with restoration work of local infrastructure) is situated in a place where the average air dose rate exceeds 2.5 μSv/h, and workers engage in work by which they are expected to stay in the place for 40 hours or longer per month, or (2) workers engage in conveyance of loads (construction machinery, construction materials, soil, gravel, etc.) associated with restoration work of local infrastructure in a place where the average air dose rate exceeds 2.5 μSv/h. なお、平均空間線量率二・五マイクロシーベルト毎時を超える地域を単に通過する場合については、滞在時間が限られることから、特定線量下業務には該当しないこと。 Only passing through an area where the average air dose rate exceeds 2.5 μSv/h does not fall underwork at the designated dose rate because the time of stay there is limited. ハ　エックス線装置等の管理された放射線源により二・五マイクロシーベルト毎時を超えるおそれのある場所については、「特定線量下業務」が事故由来放射性物質により二・五マイクロシーベルト毎時を超える場所における業務に限られることから、引き続き電離則第３条第１項の管理区域として取り扱うこと。 (c) Places where the average air dose rate exceeds 2.5 μSv/h due to a controlled radiation source, such as an X-ray device, are also handled as controlled areas as provided for in Article 3, paragraph (1) of the Ionizing Radiation Regulation because "work at the designated dose rate" are limited to operations to be performed in places with an average air dose rate in excess of 2.5 μSv/h due to accident-derived radioactive materials. 第３　被ばく線量管理の対象及び方法 Section 3 Subjects and Methods of Radiation Exposure Dose Control Ａ　基本原則 A Basic principles （一）　特定線量事業者は、特定線量下業務に従事する労働者（以下「特定線量下業務従事者」という。）又はその他の労働者が電離放射線を受けることをできるだけ少なくするように努めること。 (1) An employer engaging in business at the designated dose rate endeavors to minimize the exposure to ionizing radiation of workers who engage in work at the designated dose rate (hereinafter referred to as "workers engaging in work at the designated dose rate") or other workers. （二）　特定線量下業務を実施する際には、特定線量下業務従事者の被ばく低減を優先し、あらかじめ、作業場所における除染等の措置が実施されるように努めること。 (2) When performing work at the designated dose rate, the employer gives the highest priority to the reduction of the exposure to ionizing radiation of workers engaging in work at the designated dose rate, and endeavor to ensure that measures, such as decontamination, are taken in advance in workplaces. イ　（一）は、国際放射線防護委員会（ＩＣＲＰ）の最適化の原則に基づき、事業者は、作業を実施する際、被ばくを合理的に達成できる限り低く保つべきであることを述べたものであること。 (a) The provision of (1) above states that employers should keep exposure to radiation during work as low as reasonably achievable based on the principles of optimization of the International Commission on Radiological Protection (ICRP). ロ　（二）については、ＩＣＲＰで定める正当化の原則（以下「正当化原則」という。）から、一定以上の被ばくが見込まれる作業については、被ばくによるデメリットを上回る公益性や必要性が求められることに基づき、特定線量業務従事者の被ばく低減を優先して、作業を実施する前にあらかじめ、除染等の措置を実施するよう努力する必要があること。 (b) The provision of (2) above states that when performing work that is expected to cause a certain level of radiation exposure, it is necessary to give the highest priority to the reduction of the exposure of workers engaging in work at the designated dose rate to radiation and endeavor to take measures, such as decontamination, before performing the work, in view of the principles of justification set by ICRP (hereinafter referred to as the "principles of justification") which requires public benefits and needs outweighing the demerits of radiation exposure in performing the work. ハ　正当化原則に照らし、製造業、商業等の事業を行う事業者は、労働時間が長いことに伴って被ばく線量が高くなる傾向があること、必ずしも緊急性が高いとはいえないことも踏まえ、あらかじめ、作業場所周辺の除染等の措置を実施し、可能な限り線量低減を図った上で、原則として、被ばく線量管理を行う必要がない空間線量率（二・五マイクロシーベルト毎時以下）のもとで作業に就かせることが求められること。 (c) In light of the principles of justification and considering the fact that radiation exposure doses tend to increase in proportion to working hours and that the urgency of work in a manufacturing or commercial business, etc. is not necessarily high, an employer engaging in such a business is required to take measures, such as decontamination, in and around workplaces in advance to minimize doses and, in principle, enable workers to work under an air dose rate that does not require radiation exposure dose control (2.5 μSv/h or below). なお、原子力災害対策本部が製造業等の再開を管理する平均空間線量率が三・八マイクロシーベルト毎時以下の地域では、屋内の空間線量率は建物の遮へい効果によりその約四割の約一・五マイクロシーベルト毎時以下であると想定されることから、作業開始前に除染等の措置を適切に実施すれば、製造業等の屋内作業が特定線量下業務に該当することはないと見込まれること。 Since it is assumed that in areas where the average air dose rate set by the Nuclear Emergency Response Headquarters to control the resumption of manufacturing businesses, etc. is 3.8 μSv/h or below, the indoor air dose rate is approximately 40% of this value, or approximately 1.5 μSv/h or below, due to the shielding effect of buildings, indoor work in manufacturing businesses, etc. is not expected to fall under work at the designated dose rate if measures, such as decontamination, are appropriately taken before starting work. Ｂ　線量の測定 B Measurement of doses （一）　特定線量事業者は、作業場所の平均空間線量率が二・五マイクロシーベルト毎時を超える場所において労働者を特定線量下業務に就かせる場合は、個人線量計により外部被ばく線量を測定すること。 (1) When an employer engaging in business at the designated dose rate directs workers to perform work at the designated dose rate in workplaces where the average air dose rate exceeds 2.5 μSv/h, the employer measures the external radiation exposure doses of the workers by means of personal dosimeters. （二）　自営業者、個人事業者については、被ばく線量管理等を実施することが困難であることから、あらかじめ除染等の措置を適切に実施する等により、特定線量下業務に該当する作業に就かないことが望ましいこと。 (2) Given the difficulty for self-employed workers and sole proprietors in controlling radiation exposure doses, it is desirable that they avoid engaging in work falling under work at the designated dose rate by appropriately taking measures, such as decontamination, in advance. イ　やむをえず、特定線量下業務を行う個人事業主、自営業者については、特定線量下業務を行う事業者とみなして、このガイドラインを適用すること。 (a) Self-employed workers and sole proprietors who inevitably have to perform work at the designated dose rate are deemed as employers engaging in a business at designated dose rate, and these Guidelines apply to them. ロ　ボランティアについては、作業による実効線量が一ミリシーベルト／年を超えることのないよう、作業場所の平均空間線量率が二・五マイクロシーベルト毎時（週四十時間、五十二週換算で、五ミリシーベルト／年相当）以下の場所であって、かつ、年間数十回（日）の範囲内で作業を行わせること。 (b) Volunteers are permitted to work in workplaces where the average air dose rate is 2.5 μSv/h (equivalent to approximately 5 mSv/year when working 40 hours per week for 52 weeks) or below, and within several dozen times (days) in a year so that the effective dose caused by the work will not exceed 1 mSv/year. Ｃ　被ばく線量限度 C Radiation exposure dose limits （一）特定線量事業者は、２の（一）で測定された労働者の受ける実効線量の合計が、次のアからウまでに掲げる限度を超えないようにすること。 (1) An employer engaging in business at the designated dose rate endeavors to keep the total of the effective doses of workers as measured in 2 (1) below the limits listed in (a) to (c) below. イ　男性及び妊娠する可能性がないと診断された女性は、五年間につき百ミリシーベルト、かつ、一年間に五十ミリシーベルト (a) Male workers and female workers diagnosed as being unable to conceive: 100 mSv per five years and 50 mSv per year ロ　女性（妊娠する可能性がないと診断されたものおよびウのものを除く。）は、三月間につき五ミリシーベルト (b) Female workers (excluding those diagnosed as being unable to conceive and those stated in (c) below): 5 mSv per three months ハ　妊娠と診断された女性は、妊娠中に腹部表面に受ける等価線量が二ミリシーベルト (c) Pregnant female workers: 2 mSv in equivalent dose on the abdominal surface during the pregnancy period （二）　特定線量事業者は、電離則第三条で定める管理区域内において放射線業務に従事した労働者、除染等業務に従事した労働者を特定線量下業務に就かせるときは、当該労働者が放射線業務又は除染等業務で受けた実効線量と２の（一）により測定された実効線量の合計が（一）の限度を超えないようにすること。 (2) When an employer engaging in business under a lower dose rate directs workers who engaged in radiation work in controlled areas provided for in Article 3 of the Ionizing Radiation Regulation or workers who engaged in decontamination and related works to engage in works under a lower dose rate, the employer keeps the total of the effective dose the workers were exposed to during the radiation work or decontamination and related works and the effective dose as measured in 2 (1) at or below the limits specified in (1). （三）　特定線量事業者は、（一）及び（二）に規定する被ばく線量管理を行うため、特定線量下業務従事者に対し、雇い入れ又は特定線量下業務への配置換えの際、被ばく歴の有無（被ばく歴を有する者については、作業の場所、内容及び期間その他放射線による被ばくに関する事項）を当該労働者が前の事業者から交付された線量の記録（労働者がこれを有していない場合は前の事業場から再交付を受けさせること。）により調査すること。 (3) To perform radiation exposure control provided for in (1) and (2), an employer engaging in business at the designated dose rate investigates whether workers engaging in work at the designated dose rate have a radiation exposure history (for those who have a radiation exposure history, the place, type, and period of work and other matters relating to radiation exposure are made known to the employer) at the time of employment or transfer to works at the designated dose rate based on the dose records issued to these workers from the previous employers (if workers do not have a dose record, the employer asks them to have the dose record reissued by the previous employers). （四）　（一）のアの「五年間」については、異なる複数の事業場において特定線量下業務に従事する労働者の被ばく線量管理を適切に行うため、全ての特定線量下業務を事業として行う事業場において統一的に平成二十四年一月一日を始期とし、「平成二十四年一月一日から平成二十八年十二月三一日まで」とすること。平成二十四年一月一日から平成二十八年十二月三十一日までの間に新たに特定線量下業務を事業として実施する事業者についても同様とし、この場合、事業を開始した日から平成二十八年十二月三十一日までの残り年数に二十ミリシーベルトを乗じた値を、平成二十八年十二月三十一日までの被ばく線量限度とみなして関係規定を適用すること。 (4) To properly control the radiation exposure doses of workers engaging in work at the designated dose rate in multiple different places of businesses, the initial date of the period of "five years" prescribed in (1) (a) above should be January 1, 2012 uniformly for all relevant places of businesses performing works at the designated dose rate, and the exposure dose should be controlled during the period "from January 1, 2012 to December 31, 2016". This rule also applies to employers who started or will start a new work at the designated dose rate as a business between January 1, 2012 and December 31, 2016. In this case, the number of years from the day the business commenced till December 31, 2016, multiplied by 20mSv is deemed as the exposure dose limit until December 31, 2016, and relevant regulations should apply accordingly. （五）　（一）のアの「一年間」については、「五年間」の始期の日を始期とする一年間であり、「平成二十四年一月一日から平成二十四年十二月三十一日まで」とすること。なお、平成二十四年一月一日以降、平成二十四年六月三十日までに受けた線量を把握している場合は、それを平成二十四年７月一日以降に被ばくした線量に合算して被ばく管理すること。 (5) The time period of "one year" prescribed in (1) (a) above means the one-year period commencing on the initial day of "five years" and the period is "from January 1, to December 31, 2012". When the dose received from January 1, 2012 until June 30, 2012 is ascertained, radiation exposure control is performed by adding the dose to the exposure dose from July 1, 2012. （六）　特定線量事業者は、「一年間」又は「五年間」の途中に新たに自らの事業場において特定線量下業務に従事することとなった労働者について、特定線量下業務の開始前に、当該「一年間」又は「五年間」の始期より当該特定線量下業務に従事するまでの被ばく線量を当該労働者が前の事業者から交付された線量の記録（労働者がこれを有していない場合は前の事業場から再交付を受けさせること。）により確認すること。 (6) When any worker of an employer engaging in business at the designated dose rate newly engages in works at the designated dose rate in the employer's place of business at any point in "one year" or "five years," the employer confirms the radiation exposure dose from the start of this "one year" or "five years" until the day the worker starts engaging in the works at the designated dose rate, based on the dose record issued to the worker from the previous employer (if the worker does not have a dose record, the employer asks the worker to have the dose record reissued by the previous employer). （七）　（三）及び（四）の規定に関わらず、放射線業務を主として行う事業者については、事業場で統一された別の始期により被ばく線量管理を行っても差し支えないこと。 (7) Notwithstanding the provisions of (3) and (4), an employer who primarily engages in radiation work may perform radiation exposure dose control from another timing of the start that is uniformly applied in the employer's place of business. （八）　特定線量事業者は、（四）及び（五）の始期を特定線量下業務従事者に周知させること。 (8) An employer engaging in business at the designated dose rate informs workers engaging in work at the designated dose rate of the start of timing prescribed in (4) and (5). Ｄ　線量の測定結果の記録等 D Records of measurement results of doses （一）特定線量事業者は、二の測定又は計算の結果に基づき、次に掲げる特定線量下業務従事者の被ばく線量を算定し、これを記録し、これを三十年間保存すること。また、三の（三）の調査の結果についても同様とすること。ただし、五年間保存した後に当該記録を、又は当該特定線量下業務従事者が離職した後に当該特定線量下業務従事者に係る記録を、厚生労働大臣が指定する機関に引き渡すときはこの限りではないこと。この場合、記録の様式の例として、様式一があること。 (1) An employer engaging in business under at the designated dose rate calculates the radiation exposure doses of the workers engaging in work at the designated dose rate listed in the following items based on the measurement or calculation results referred to in 2 above, record the calculated results, and keep the records for 30 years. These provisions also apply to investigation records referred to in 3 (3); provided, however, that this provisions do not apply when the employer hands over the records to the organization designated by the Minister of Health, Labour and Welfare after these records are kept for five years or after the workers engaging in work at the designated dose rate are terminated.
