Question 409: In complying with the 10 CFR 19.13 (c) report request, is it acceptable to report on a Form-4 dose received in the current year as one monitoring period and dose received in prior years as another monitoring period even if the prior years monitoring period exceeds one year?
Answer: Yes. However, it should be recognized that this report should include records of doses received during planned special exposures, accidents, and emergency conditions as shown in the records maintained in accordance with 10 CFR 20.2106. If there have been no planned special exposures or overexposures, a statement to that effect should be provided.
