放射性核素

The contributions of photon radiations are ignored because they are negligible compared to the contributions of the particle radiations, or can be calculated and added to the S-values using MIRD formulae.

如果细胞群较小，则光子的剂量贡献忽略不记。细胞群中每个细胞内的放射性活度相同。计算得到细胞群中各个周围细胞中心到靶细胞中心的距离和周围细胞中的核素对靶细胞的剂量贡献。

An investigation on radionuclide accumulation by native halophytes and its influencing factors,plant variety and parts,soil K content and profile contribution of radionuclide,was carried out for the feasibility of radionuclide phytoremediation at a radionuclide contamination site,in China.

The nuclides that were dispersed and settled as "fallout" varied in their effect upon living plants and animals.

作为&放射性尘埃&在大气中弥散和沉降的各种核素对生长着的动植物有着不同的影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
