Personal Alpha Dosimetry
The Radiation Safety Institute of Canada uses world-class, patented technology in our personal alpha dosimetry (PAD) service. There is simply no better system available in Canada for monitoring the radiation exposure of individual workers from radon and thoron progeny and from long-lived radioactive dust (LLRD).
- A reliable, efficient and fully integrated personal radiation exposure monitoring system
- The PAD is lightweight, self-contained and durable – quite simply the most accurate and convenient technology available on the market
- Government certified and licensed by the Canadian Nuclear Safety Commission (CNSC)
- Best of all, every aspect of the Institute’s PAD system is backed by our world-class scientific and technical staff

Originally developed in 1983, the Radiation Safety Institute of Canada’s Personal Alpha Dosimeter has become an indispensable safety tool for the uranium mining industry and companies involved in the clean-up of radioactive waste sites. In fact, our PAD service is the only licensed radiation dosimetry service in North America capable of measuring the actual exposure of individual workers to alpha radiation from radon and thoron progeny and LLRD.
How the PAD System works
The Radiation Safety Institute of Canada’s PAD system consists of a dosimeter head and an air sampling unit. The PAD is worn on a worker’s belt. At the end of each month, the dosimeter head is removed and replaced by a fresh head. The used head is sent to our National Laboratories in Saskatoon, Saskatchewan for processing. Transport of the used heads is easy, quick and efficient.
The PAD Service includes laboratory analysis, technical support, on-site equipment, quality assurance, quality control and timely reporting of results, including early alerts. Results are sent to clients and also sent to Health Canada’s National Dose Registry (NDR), as required.

IAEA Mission to Assess Nuclear Safety in Japan
A January 17, 2012 report on the IAEA Web site states that an International Atomic Energy Agency (IAEA) International Complementary Safety Assessment Review Mission will conduct a visit to Japan next week to assist the nation’s development of a comprehensive assessment of the safety of existing nuclear power plants.
Arranged at the request of the Japanese government, the 10-member team will consist of IAEA nuclear experts and international specialists who will hold meetings with Japanese officials in Tokyo and conduct a site visit to the Ohi Nuclear Power Plant in Fukui Prefecture.
Fukushima Nuclear Site Finally Stabilized
A December 16, 2011 report by the International Atomic Energy Agency (IAEA) has welcomed the announcement by Japanese Prime Minister Yoshihiko Noda of the “cold shutdown condition” of the Fukushima nuclear site. According to Prime Minister Noda, the site is in a “stable state”, and the release of radioactive materials is “under control”.
Radiation Safety in The Workplace Podcast, Part II
The Canadian Centre for Occupational Health and Safety (CCOHS), in collaboration with the Radiation Safety Institute of Canada, has just released Part II of a special two-part mini-series Podcast on radiation in the workplace. In this episode, our Radiation Scientist Claire Cohalan, focuses on safety and how workers can protect themselves from radiation in the workplace.
