Nuclear power currently provides approximately 15% of Canada's electricity. In order to guarantee radiation protection for the workers at nuclear power stations, it is of great importance to have accurate radiation measurement instruments and dose computation tools. There are technical limitations in the current radiation detection and measurement instruments, particularly for low dose mixed radiation fields (for example, beta and gamma mixed fields). To address the limitations, this Alliance research aims to develop advanced radiation detectors and instrumentation. The developed radiation detectors and signal processing systems will be eventually used at nuclear power plants. Another important challenge we face in nuclear power industry is to understand the true effects and risks of low-level radiation exposure taking account of the new discoveries in this area. Satisfying the intersecting interests of nuclear workers, the public and the environment is only possible in an atmosphere where trust is high and uncertainty is low. Hence, this research will seek to correlate low radiation doses measured with the newly developed detectors, with impacts on populations. The research team will lead modern research into long-term low dose mechanisms. This is the key to developing bio-indicators and bio-sensors which can alert us to subtle impacts which may not be immediately observable but can have insidious effects which later become important.

目前，核能占加拿大电力的15%。为了保证核电站工作人员的辐射防护，准确的辐射测量仪器和剂量计算工具是非常重要的。目前的辐射探测和测量仪器存在技术限制，特别是对于低剂量混合辐射场（例如，β和γ混合场）。为了解决这些局限性，该联盟的研究旨在开发先进的辐射探测器和仪器。开发的辐射探测器和信号处理系统最终将用于核电站。我们在核电工业中面临的另一个重要挑战是了解低水平辐射照射的真实影响和风险，同时考虑到这一领域的新发现。只有在信任度高、不确定性低的环境中，才有可能满足核工作人员、公众和环境的交叉利益。因此，这项研究将寻求将新开发的探测器测得的低辐射剂量与对人口的影响联系起来。该研究小组将引领现代研究进入长期低剂量机制。这是开发生物指示器和生物传感器的关键，这些指示器和传感器可以提醒我们注意可能无法立即观察到的微妙影响，但可能产生后来变得重要的潜在影响。
