摘  要：
用~(60)Coγ射线辐照文蛤幼贝,研究其对文蛤生长及抗病性的影响。A组预试验结果表明:低剂量~(60)Coγ射线辐照对促生长有效,高剂量辐射抑制了文蛤生长。B组正式试验辐照剂量(低剂量)3.23×10-7～25.80×10-7C/kg。低剂量辐射试验结果表明:46d后,试验组平均壳高及平均体重均高于对照组,分别增加15%～21%和16%～26%;276d后,试验组的平均壳高较对照组增加17%～23%,且试验组文蛤的抗病性远优于对照组。6.45×10-7～19.35×10-7C/kg低剂量为促进文蛤幼贝生长、提高抗病性的有效剂量范围。

摘  要：
Juveniles of Meretrix meretrix Linnaeus were treated with ~(60)Co γ-rays radiation in order to study effects on their growth and resistance.The research was designed into two parts named A and B,both of which were composed of one blank group and five test groups.After cultured in the sea for 46 days,A showed that low-dose ~(60)Co γ-ray radiation was good for promoting growth,while high-dose radiation of 95.46×10-7 C/kg to 2363×10-7 C/kg restrained the juveniles'growth.Therefore,suitable doses ranged from 0×10-7 C/kg to 25.80×10-7 C/kg were selected to design B,and the juveniles were cultured for 46 and 276 days respectively.B showed average height and average weight of five test groups irradiated by ~(60)Co γ-ray were higher than blank group after 46 days cultured,and the two indexes were increased by 15%～21% and 16%～26% respectively.Continued to be cultured for 276 days in the sea,test groups were increased by 17%～23%,and irradiated test groups'resistance excelled the blank group which was not irradiated.The juveniles were irradiated by ~(60)Co γ-ray ranged from 6.45×10-7 C/kg to 19.35×10-7 C/kg,which effect the growth and resistance greatly.Consequently,the suitable dosage of irradiation to juveniles was 6.45×10-7 C/kg～19.35×10-7 C/kg.
