Radiation protection of workers in mines

The ICRP 47 describes the principles and applications of methods by which radiation hazards may be controlled in mines, particularly in the uranium mining industry. Details are given of the dose limits for individual exposures from Rn-222, Rn-220 and their decay products and ore dust. The measures described for controlling exposure are choice of mining method, source isolation, mechanical ventilation, air cleaning, backfitting, personal protective equipment and organization of work. Recommendations for air monitoring for radon and radon decay products and ore dust, external exposure monitoring and monitoring the quality of protective measures systems are also presented. Finally, recommendations on medical surveillance of miners are given. (orig./HP) With 8 tabs
