OAR 333-105-0560
Radiation Safety Requirements: Personnel Monitoring

(1)

The licensee may not permit any individual to act as a radiographer or a radiographer’s assistant unless, at all times during radiographic operations, each individual wears, on the trunk of the body, a combination of direct reading dosimeter, an alarming ratemeter, and a personnel dosimeter that is processed and evaluated by an accredited National Voluntary Laboratory Accreditation Program (NVLAP) processor. At permanent radiographic installations where other appropriate alarming or warning devices are in routine use, or during radiographic operations using radiation machines, the use of an alarming ratemeter is not required.

(a)

Pocket dosimeters must have a range from zero to two millisieverts (200 mrem) and must be recharged at the start of each shift. Electronic personal dosimeters may only be used in place of ion-chamber pocket dosimeters.

(b)

Each personnel dosimeter must be assigned to and worn by only one individual.

(c)

Film badges must be exchanged and processed at periods not to exceed one month and other personnel dosimeters processed and evaluated by an accredited NVLAP processor must be replaced at periods not to exceed three months.

(d)

After replacement, each personnel dosimeter must be returned to the supplier for processing within 14 calendar days of the end of the monitoring period, or as soon as practicable. In circumstances that make it impossible to return each personnel dosimeter in 14 calendar days, such circumstances must be documented and available for review by the Authority.

(2)

Direct reading dosimeters such as pocket dosimeters or electronic personal dosimeters, must be read and the exposures recorded at the beginning and end of each shift, and records must be maintained in accordance with 333-105-0700 (Recordkeeping Requirements: Records of Personnel Monitoring).

(3)

Pocket dosimeters, or electronic personal dosimeters, must be checked at periods not to exceed 12 months for correct response to radiation, and records must be maintained in accordance with 333-105-0700 (Recordkeeping Requirements: Records of Personnel Monitoring)(1). Acceptable dosimeters must read within plus or minus 20 percent of the true radiation exposure.

(4)

If an individual’s pocket dosimeter is found to be off-scale, or the electronic personal dosimeter reads greater than two millisieverts (200 mrem), the individual’s personnel dosimeter must be sent for processing within 24 hours. In addition, the individual may not resume work associated with the use of sources of radiation until a determination of the individual’s radiation exposure has been made. This determination must be made by the radiation safety officer or the radiation safety officer’s designee. The results of this determination must be included in the records maintained in accordance with 333-105-0700 (Recordkeeping Requirements: Records of Personnel Monitoring).

(5)

If a personnel dosimeter is lost or damaged, the worker must cease work immediately until a replacement personnel dosimeter is provided and the exposure is calculated for the time period from issuance to loss or damage of the personnel dosimeter. The results of the calculated exposure and the time period for which the personnel dosimeter was lost or damaged must be included in the records maintained in accordance with 333-105-0700 (Recordkeeping Requirements: Records of Personnel Monitoring).

(6)

Dosimetry reports received from the accredited NVLAP personnel dosimeter processor must be retained in accordance with 333-105-0700 (Recordkeeping Requirements: Records of Personnel Monitoring).

(7)

Each alarming ratemeter must:

(a)

Be checked to ensure that the alarm functions properly before using at the start of each shift;

(b)

Be set to give an alarm signal at a preset dose rate of five millisieverts (500 mrem per hour) with an accuracy of plus or minus 20 percent of the true radiation dose rate;

(c)

Require special means to change the preset alarm function; and

(d)

Be calibrated at periods not to exceed 12 months for correct response to radiation. The licensee must maintain records of alarming ratemeter calibrations in accordance with 333-105-0700 (Recordkeeping Requirements: Records of Personnel Monitoring)(2).
