在农业上利用适当剂量的放射性同位素照射种子(叫辐射育种),能使农作物抗病能力提高,实现良种化,增加产量。但是,如果在研究工作中使用的钴~(60)射性线源量值不统一,辐射剂量数据互不一致,就会影响科学研究工作的深入和成果的推广。沈阳市计量标准局放射性室于1973年4月对东北三个农业科学院使用的钴~(60)射线源进行了检定。通过检
In agriculture, the use of appropriate doses of radioactive isotope irradiation seeds (called radiation breeding), can make the crop disease resistance, improve seed production, increase production. However, if the amount of cobalt 60 radioactive source used in the research is not uniform and the radiation dose data are inconsistent with each other, it will affect the deepening of scientific research and the promotion of the results. Shenyang Bureau of Metrology Standards radioactive chamber in 1973 April on the northeast three Academy of Agricultural Sciences cobalt ~ (60) ray source was tested. Passed seized
