It covers radiological and nuclear hazards, RAM storage and use surveys, medical and industrial diagnostic X-ray scatter surveys, swipe tests, field sample analysis, and isotope decay. The package requires documenting measurements, evaluating exposure, comparing results with standards, and completing survey results.

Topics covered

  • Ionizing radiation hazards
  • RAM storage and use surveys
  • X-ray scatter surveys
  • Radiological source swipe tests
  • Field analysis of samples
  • Isotope decay identification

Questions and answers

How far from a surface should gamma or X-ray radiation be measured?

Take measurement 30 cm (12 inches) from any surface displaying radiation penetration. (paragraph 3)

What should be done with background readings during radiation surveys?

Subtract background readings from readings at each location (in order to obtain net exposure rates). (paragraph 5)

What may replace the occupancy factor when better data is available?

If more reliable source of occupancy data is available, it may be used instead of the OF as long as it is documented and defensible. (paragraph 4)
