Background: In Japan, new regulations that revise the dose limit for the lens of the eye (hereafter the lens), operational quantities, and measurement positions for the lens dose were enforced in April 2021. Based on the international safety standard

Publikováno v: International journal of radiation biology.

In April 2011, the International Commission on Radiological Protection recommended reducing the occupational equivalent dose limit for the lens. Such a new occupational lens dose limit has thus far been implemented in many countries, and there are ex

Present status and practical issues on dosimetry for the lens of the eye at JAEA MOX fuel facilities

Autor: Norio Tsujimura, Takumi Yamazaki, Chie Takada

Publikováno v: Journal of Nuclear Science and Technology. 58:40-44

At Japan Atomic Energy Agency (JAEA) MOX fuel facilities, a worker usually wears a protective lead apron; therefore, the dose to the lens of the eye (lens dose) outside the apron is higher than tha...

CONVERSION FACTOR FROM DOSEMETER READING TO AIR KERMA FOR NUCLEAR WORKER USING ANTHROPOMORPHIC PHANTOM FOR FURTHER CONVERSION FROM AIR KERMA TO ORGAN-ABSORBED DOSE

Autor: Shin Saigusa, Norio Tsujimura, Hiroshige Furuta, Shin’ichi Kudo, Akemi Nishide

Publikováno v: Radiation Protection Dosimetry

Estimation of cancer risk based on the organ-absorbed dose is underway for the Japanese Epidemiological Study on Low-Dose Radiation Effects (J-EPISODE). The reconstruction method for the organ-absorbed dose follows the approach adopted in the IARC 15

Radiation exposure to the lens of the eye for Japanese nuclear power plant workers

Autor: Sumi Yokoyama, Hideo Tatsuzaki, Yoshihiko Tanimura, Hiroshi Yoshitomi, Shigekazu Hirao, Katsunori Aoki, Shuichi Tachiki, Iwao Ezaki, Katsuya Hoshi, Norio Tsujimura

Publikováno v: Journal of radiological protection : official journal of the Society for Radiological Protection. 42(3)

In Japan, the radiation-dose limit for the lens of the eye was revised in April 2021. Consequently, for workers, the numerical values of the equivalent dose to the lens of the eye are equal to those of the effective dose. Radiation workers, radiation
