Overview: FEMA IS-302 course is a series of modules that can serve as a refresher training course for those students already proficient in radiological response.
FEMA IS-302 includes the following topics: radiological basics, biological effects, hazard recognition (markings, labels, and placards), initial response actions, radioactive material shipping packages, on-scene patient handling, radiological terminology and units, assessing package integrity, radiation detection instrumentation, and radiological decontamination.
FEMA IS-302 test answers
Each time this test is loaded, you will receive a unique set of questions and answers. The test questions are scrambled to protect the integrity of the exam.
Question 1. A sealed radioactive source used in radiography operations would be an example of a special form radioactive material.
Question 2. While surveying with a contamination monitor, you hear an increase in the count rate. What should you do?
A. Finish the survey with audible turned off to avoid distraction.
B. Pause for 5-10 seconds over the area to provide adequate time for instrument response.
C. Stop surveying, cover the area, leave, and wait for State Radiological Control Personnel to advise.✅
