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

这项建议是对先前IRC的延续，该IRC制定了暴露在鱼的急性外部低剂量伽马和X射线照射下的非人类物种辐射应激的生物指标。更新提案的目标是扩大用于包括急性和长期暴露于阿尔法、贝塔和伽马放射同位素的剂量学方法和辐射类型，这些放射性同位素涉及使用坎杜反应堆开采和生产核能。重点将放在铀衰变产物(包括氡子体)、铯和氚。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，要么是因为使用核能发电的日常过程，要么是因为核试验或切尔诺贝利事故的污染。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
