小剂量~(137)铯-γ射线照射柞蚕卵,同中子源、~(60)钴-γ源辐照一样,有显著增产作用,小区试验增产14—34%,大面积生产鉴定试验增产20%左右。~(137)铯-γ具有半衰期长、射线单一、能量低、易于防护、无环境污染、操作简便,价格低廉等特点。可实行流动照射和固定照射,有利于普及核技术在柞蚕生产上应用。我们从1973—1980年进行了小区试验、生产鉴定,并大面积推广,肯定了铯源照射柞蚕卵增产的有效剂量和照射效果。
The irradiation of small dose 137Cs with γ-ray on tussah eggs showed the same yield as that of neutron source and 60Co-γ source. The plot test increased yield by 14-34% and large-area production test increased About 20%. ~ (137) cesium-γ has a long half-life, a single ray, low energy, easy protection, no environmental pollution, easy operation, low prices and so on. Flowing irradiation and fixed irradiation can be implemented, which is beneficial to the popularization of nuclear technology in the application of tussah production. From 1973 to 1980, we conducted community trials, identification of production, and large-scale promotion, affirmed the effective dose and irradiation effect of cesium source irradiation tussah egg production.
