OAR 333-120-0100
Radiation Dose Limits: Occupational Dose Limits For Adults


(1)

Each licensee or registrant must control the occupational dose to individual adults, except for planned special exposures under OAR 333-120-0150 (Radiation Dose Limits: Planned Special Exposures), to the following dose limits:

(a)

An annual limit, which is the more limiting of:

(A)

The total effective dose equivalent being equal to 0.05 Sv (5 rem); or

(B)

The sum of the deep-dose equivalent and the committed dose equivalent to any individual organ or tissue other than the lens of the eye being equal to 0.5 Sv (50 rem).

(b)

The annual limits to the lens of the eye, to the skin, and to the extremities that are:

(A)

A lens dose equivalent of 0.15 Sv (15 rem); and

(B)

A shallow-dose equivalent of 0.50 Sv (50 rem) to the skin of the whole body or to the skin of any extremity.

(2)

Doses received in excess of the annual limits, including doses received during accidents, emergencies, and planned special exposures, must be subtracted from the limits for planned special exposures, as defined in OAR 333-100-0005 (Definitions), that the individual may receive during the current year OAR 333-120-0150 (Radiation Dose Limits: Planned Special Exposures)(5)(a) and during the individual’s lifetime OAR 333-120-0150 (Radiation Dose Limits: Planned Special Exposures)(5)(b).

(3)

When the external exposure is determined by measurement with an external personal monitoring device, the deep-dose equivalent must be used in place of the effective dose equivalent, unless the effective dose equivalent is determined by a dosimetry method approved by the Authority. The assigned deep-dose equivalent must be for the part of the body receiving the highest exposure. The assigned shallow-dose equivalent must be the dose averaged over the contiguous ten square centimeters of skin receiving the highest exposure. The deep-dose equivalent, lens-dose equivalent, and shallow-dose equivalent may be assessed from surveys or other radiation measurements for the purpose of demonstrating compliance with the occupational dose limits, if the individual monitoring device was not in the region of highest potential exposure, or the results of individual monitoring are unavailable:

(a)

The deep-dose equivalent, lens dose equivalent and shallow-dose equivalent may be assessed from surveys or other radiation measurements for the purpose of demonstrating compliance with the occupational dose limits, if the individual monitoring device was not in the region of highest potential exposure, or the results of individual monitoring are unavailable; or

(b)

When a protective apron is worn while working with medical fluoroscopic equipment and monitoring is conducted, the effective dose equivalent for external radiation must be determined as follows:

(A)

When only one individual monitoring device is used and it is located at the neck outside the protective apron, the reported deep dose equivalent must be the effective dose equivalent for external radiation; or

(B)

When only one individual monitoring device is used and it is located at the neck outside the protective apron, and the reported dose exceeds 25 percent of the limit specified in section (1) of this rule the reported deep dose equivalent value multiplied by 0.3 must be the effective dose equivalent for external radiation; or

(C)

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 must 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 1.5 and the deep dose equivalent reported for the individual monitoring device located at the neck outside the protective apron multiplied by 0.04.

(4)

Derived air concentration (DAC) and annual limit on intake (ALI) values are presented in 10 CFR Part 20 Table 1 of Appendix B to 20.1001 to 20.2401 and may be used to determine the individual’s dose (OAR 333-120-0650 (Records of Individual Monitoring Results)) and to demonstrate compliance with the occupational dose limits.

(5)

In addition to the annual dose limits, the licensee must limit the soluble uranium intake by an individual to 10 milligrams in a week in consideration of chemical toxicity (see 10 CFR Part 20 footnote 3 of Appendix B to 20.1001 to 20.2401).

(6)

When monitoring is required by OAR 333-120-0210 (Surveys and Monitoring: Conditions Requiring Individual Monitoring of External and Internal Occupational Dose) each licensee or registrant must reduce the dose that an individual may be allowed to receive in the current year by the amount of occupational dose received while employed by any other person (OAR 333-120-0630 (Records: Determination of Prior Occupational Dose)(5)).

(7)

The licensee must reduce the dose that an individual may be allowed to receive in the current year by the amount of occupational dose received while employed by any other person.
