The creation of the Commission followed the coming into force of the Nuclear Safety and Control Act on May 31, 2000. The new act replaced the Atomic Energy Control Act adopted in 1946. The revamped law, strengthened regulations and increased enforcement powers represented a major overhaul of Canada's nuclear regulatory regime. The new legislation now has more focus on the fields of health, safety, security and environmental protection.

This kind of meter is unable to measure low energy radioisotopes like tritium (H-3). The unit is composed of a probe to detect radioactivity, the base containing the electronics, and the meter face.
