云南滇池螺蛳作为饲料的研究

A STUDY ON THE SPIRAL SHELL IN DIANCHI, YUNNAN, AS DOMESTIC FEED

本文研究了滇池螺蛳作为家禽饲料,天然放射性核素在鸡体内富集和转移的规律,结果表明:天然放射性核素U,Th,^(226)Ra在鸡肉,鸡骨,鸡蛋和蛋壳中的含量育显著差异,它们在鸡体内的富集和转移能力为Th>U>^(226)Ra,但三种放射性核素含量均低于中华人民共和国食品中放射性物质限量标准,为开发和利用滇池中的螺蛳作为家禽饲料提供了依据。

This article studies the accumulation and the metastasis of natural radioactive nuclei in thecorporal of chicken when spiral shell is used as domestic feed. The result shows that the contents of natural radioactivity nuclei U, Th, and ^(226)Ra vary with the chicken meat, chicken bone, chicken egg and egg capsule. Their accumulation and metastasis are in the orders Th>U>^(226)Ra, but the levels of the three radioactive nuclei are all below the limited levels of radioactive substances in the food standard of the People's Republic of China. This study provides a basis for developing and making use of the spiral shell as domestic feed in Dianchi, Ynnnan.
