Instructional movies were produced for assisting practical training in the special education on decontamination works.

The Ministry of Health, Labour and Welfare (MHLW) has produced, and will start releasing today, instructional movies for assisting the implementation of the special education mandated to employers to conduct decontamination works. “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 Works” (hereafter referred to as the Ionizing Radiation Ordinance for Decontamination) was put into effect on 1 January 2012 mandating employers to conduct decontamination to provide special education (lectures and practical skills, note1,2) before implementing activities such as decontamination works.

Therefore, instructional movies that discuss and illustrate key practices required for decontamination works, such as how to handle measurement instruments and how to wear protective clothes were produced with cooperation of the National Institute of Radiological Sciences. The movies consist of 23 titles (see Attachment for titles), which are available from the MHLW website ( *). They can be downloaded with a personal computer. They can be used as a support for special education, or self-directed learning for the students. The contents are shown below:
