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

这一建议是前一研究小组的延续，该小组开发了非人类物种在接受鱼类的急性外部低剂量γ和x射线照射时辐射应激的生物指标。更新建议的目标是扩大使用的剂量学方法和辐射类型，以包括在使用CANDU反应堆开采和产生核能时所涉及的α、β和γ放射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，要么是由于使用核能发电所涉及的日常过程，要么是由于核试验或切尔诺贝利事故沉降物的污染。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
