Abstract

We performed whole-genome sequencing (WGS) experiments using mice for several generations under the circumstances of radiation with low dose rates at Tokai University and the Institute for Environmental Sciences (IES) in Japan. The dose rates and total exposed periods were 0.05, 0.15, 1.0, and 20 mGy day-1 for 400, 400, 400, and 300 days, respectively. We performed a statistical analysis of the experimental results on the single-nucleotide variations (SNVs) for each mouse after four generations. The SNVs per generation were unchanged below the dose rate of 1 mGy day-1 within the 95% confidence level errors. The experimental results were reproduced by the Whack-a-Mole (WAM) model with the standard parameters obtained by the Russell mega-mouse experiments.

采用WGS技术对低剂量率小鼠实验进行统计分析,并采用打地鼠模型定量再现突变频率。
我们在日本东海大学和环境科学研究所(IES)进行了几代小鼠在低剂量率辐射环境下的全基因组测序(WGS)实验。剂量率和总暴露时间分别为0.05、0.15、1.0和20毫戈瑞天-1,持续400、400、400和300天。对每只小鼠4代后的单核苷酸变异(snv)实验结果进行统计分析。在95%置信水平误差范围内,每代SNVs低于1 mGy day-1的剂量率不变。采用罗素大鼠实验得到的标准参数,用打地鼠模型对实验结果进行了再现。

期刊介绍: The International Commission on Radiological Protection was founded in 1928 to advance for the public benefit the science of radiological protection. The ICRP provides recommendations and guidance on protection against the risks associated with ionising radiation, from artificial sources as widely used in medicine, general industry and nuclear enterprises, and from naturally occurring sources. These reports and recommendations are published six times each year on behalf of the ICRP as the journal Annals of the ICRP. Each issue provides in-depth coverage of a specific subject area.
