Regarding the above subject matter, the Bureau is now pursuing efforts toward the prevention of
to workers by means of the Ordinance on Prevention of Ionizing Radiation Hazards at Works to
Decontaminate Soil and
Wastes Contaminated by Radioactive Materials Resulting from the Great East Japan Earthquake and Related
(Ionizing Radiation Ordinance for Decontamination) as well as the Ordinance on Prevention of Ionizing
Hazards (Ionizing Radiation Ordinance).
At present, as private efforts to ensure more reliable compliance with laws, for the purpose of establishing a systematic control organization of the radiation exposure doses, etc. of workers engaged in decontamination works etc., studies had been carried out in the Committee on the Organization for Registration Control of Radiation Exposure Doses for Decontamination and Related Works, in which the primary contractors concerned have participated. This system was launched on a temporary basis on 15 November 2013, and notification was provided to each Prefectural Labour Bureau by means of the Labour Standards Bureau Notification No.1115-4.
In addition, today, as described in Attachment 1, the Committee has made a final decision about the method of the registration control system, and operation of the system is planned to start on 1 April 2014 for the decontamination works for which local governments or state organizations other than the Ministry of the Environment place an order.
The Ministry of Health, Labour and Welfare considers that this system is useful for the secure and smooth management of radiation exposure dose, as is provided in the Ionizing Radiation Ordinance for Decontamination and the Ionizing Radiation Ordinance, and as is described separately, the Bureau has revised the Guidelines on Prevention of Radiation Hazards for Workers Engaged in Decontamination Works, etc. (Labour Standards Bureau Notification No. 1222-6, 22 December 2011) in order to urge the employers concerned to participate in this system.
Therefore, each Prefectural Labour Bureau is being asked to provide notification, by suitable means, on the contents of this system to the ordering departments of the local governments and the state organizations, and employers groups etc. in its own jurisdictions in consideration of the following notices.
Notification has also been provided to the Ministry of Environment by means of Attachment 2, to the Ministry of Land, Infrastructure, Transport and Tourism as well as the Ministry of Agriculture, Forestry and Fisheries by means of Attachment 3, to employers’ groups concerned by means of Attachment 4, and to the governors of the prefectures concerned by means of Attachment 5.
