NSERC Industrial Research Chair in Effects of Ionizing Radiation on Non-human Biota

该提案是先前研究中心的延续，该研究中心开发了受外部低剂量伽马和X射线急性辐照鱼类的非人类物种的辐射压力生物指标。更新提案的目标是扩大所使用的剂量测定方法和辐射类型，以包括采矿和利用坎杜堆生产核能所涉及的α、β和γ放射性同位素的急性和慢性照射。重点将放在铀衰变产物（包括氡子体）、铯和氚上。在每一种情况下，水生生态系统的污染都是加拿大的一个环境问题，这要么是由于利用核能发电的日常过程，要么是由于核试验或切尔诺贝利事故放射性尘埃的污染。麦克马斯特团队将与

This proposal is a continuation of a previous IRC which developed bio-indicators of radiation stress in non-human species exposed to acute external low dose gamma and x-irradiation of fish. The goal of the renewal proposal is to expand the dosimetric approaches and radiation types used to include acute and chronic exposures to alpha, beta and gamma emitting radioisotopes involved in mining and generation of nuclear energy using CANDU reactors. The focus will be on uranium decay products (including radon daughters), caesium and tritium. In each case contamination of aquatic ecosystems is an environmental issue in Canada either due to the everyday processes involved in power generation using nuclear energy, or because of contamination from nuclear tests or Chernobyl accident fallout. The McMaster team will work closely with the
