为了解接触射线作业人群的营养状况,作者等于1986年3月21日至4月1日对某厂一车间的工人进行了饮食营养调查。该车间系钽、铌湿法冶炼车间,生产用矿石中含有放射性物质,主要是β射线及少量Υ射线。1977年有关部门对该车间外的地表测量结果:β粒子污染系数为4,000粒子数/100厘米~22分钟,超过国家标准最大允许值的0.3倍。
To understand the nutritional status of people exposed to radiation, the authors carried out a dietary and nutritional survey of workers in a factory-owned workshop between March 21 and April 1, 1986. The workshop is tantalum, niobium wet smelting workshop, production of ore contains radioactive substances, mainly β-ray and a small amount of γ rays. In 1977 the relevant departments of the plant surface measurements outside the shop: β particle contamination factor of 4,000 particles / 100 cm ~ 22 minutes, more than 0.3 times the maximum allowable national standard.
