Section 216-RICR-40-20-1.7 - Occupational Dose Limits

1.7.1Occupational Dose Limits for Adults

A. For the purpose of this Part, the occupational dose limits for adults are defined by 10 C.F.R. § 20.1201.

B. For sources of radiation other than radioactive material, when a protective apron is worn and monitoring is conducted as specified in §1.10.3(B) of this Part, the effective dose equivalent for external radiation shall be determined as follows:

1. When only one individual monitoring device is used and it is located at the neck outside the protective apron, and the reported dose exceeds twenty-five percent (25%) of the limit specified in §1.7.1(A) of this Part, the reported deep dose equivalent value multiplied by three tenths (0.3) shall be the effective dose equivalent for external radiation; or

2. When individual monitoring devices are worn, both under the protective apron at the waist and outside the protective apron at the neck, the effective dose equivalent for external radiation shall be assigned the value of the sum of the deep dose equivalent reported for the individual monitoring device located at the waist under the protective apron multiplied by one and one half (1.5) and the deep dose equivalent reported for the individual monitoring device located at the neck outside the protective apron multiplied by four one hundredths (0.04).

1.7.2Compliance with Requirements for Summation of External and Internal Doses

For the purpose of this Part, compliance with requirements for summation of external and internal doses is defined by 10 C.F.R. § 20.1202.

1.7.3Determination of External Dose from Airborne Radioactive Material

For the purpose of this Part, determination of external dose from airborne radioactive material is defined by 10 C.F.R. § 20.1203.

1.7.4Determination of Internal Exposure

For the purpose of this Part, determination of internal exposure is defined by 10 C.F.R. § 20.1204.

1.7.5Determination of Prior Occupational Dose

A. For the purpose of this Part, determination of prior occupational dose is defined by 10 C.F.R. § 20.2104.

B. The licensee or registrant shall retain the records of prior occupational dose and exposure history as specified in §1.7.5(A) of this Part on Agency Form RCA-2 or equivalent until the Agency terminates each pertinent license or registration requiring this record. The licensee or registrant shall retain records used in preparing Agency Form RCA-2 or equivalent for three (3) years after the record is made.

C. Upon termination of the license or registration, the licensee or registrant shall make arrangements, satisfactory to the Agency, for permanent storage of records contained on Agency Form RCA-2 or equivalent.

1.7.6Planned Special Exposures

For the purpose of this Part, planned special exposures are defined by 10 C.F.R. § 20.1206.

1.7.7Occupational Dose Limits for Minors

For the purpose of this Part, occupational dose limits for minors are defined by 10 C.F.R. § 20.1207.

1.7.8Dose Equivalent to an Embryo/Fetus

For the purpose of this Part, dose equivalent to an embryo/fetus is defined by 10 C.F.R. § 20.1208.
