Health Physics Questions and Answers - Question 73
Question 73: Table 1004 (b).2 does not include entries for "cold" neutrons, (e.g., 7 x 10E-9 MeV neutrons) which are used in experiments at some research reactor facilities. What values of the quality factor, Q, and the fluence per unit dose equivalent should be used for "cold" neutrons?
Answer: The values for "thermal neutrons" should be used until the use of other values is approved by the NRC.
