Orientation and Training
|VERSION NO.: 1.3|
Section 12 - Radioactivity
|EFFECTIVE DATE: 10-01-03||REVISED: 02-14-13|
The trainer will provide the training in various methodologies as described in the training SOP, e.g. reading, demonstrations, self-study, on the job training.
Gamma-emitting radionuclides and Strontium 90
Training samples may be reserved food samples (e.g. dried mushrooms, jam, leafy vegetables) or proficiency samples. Initial training covers analyses of analyses of gamma emitting radionuclides and Strontium 90.
The food program may include, but not limited to, the following training assignments:
- Gross alpha
- Gross beta
- Plutonium 238, 239
- What is the purpose for using the 400 mL fill line in analysis of gamma emitting radionuclides?
- Describe the separation methods utilized for Sr-89/90 in the Market Basket Analysis of Strontium 90 method.
- Describe the sample preparation for the analysis of tritium by liquid scintillation analysis.
