4.3.9 Radiation and Radiological Protection Fundamentals

Training should provide trainees with the requisite knowledge and skills to perform the

following:

Describe the operating principle for radiation detection instruments such as

ionization chamber

proportional counter

Geiger-Meller tube

scintillation.
