Part 350 - RADIATION SAFETY REQUIREMENTS FOR INDUSTRIAL RADIOGRAPHIC OPERATIONS
Subpart C - PERSONAL RADIATION SAFETY REQUIREMENTS FOR RADIOGRAPHERS AND RADIOGRAPHER TRAINEES
Section 350.2030 - Personnel Monitoring Control
Current through Register Vol. 48, No. 12, March 22, 2024
a) The licensee or registrant shall not permit any individual to act as a radiographer or as a radiographer trainee unless, at all times during radiographic operations, each individual wears, on the trunk of the body, a direct reading pocket ionization chamber (i.e., pocket dosimeter) and an individual monitoring device (i.e., personnel dosimeter). Each device shall be assigned to and worn by only one individual.
b) Pocket ionization chambers (i.e., pocket dosimeters) shall meet the criteria in ANSI N322-1997, "Inspection, Test, Construction, and Performance Requirements for Direct Reading Electrostatic/Electroscope Type Dosimeters", published in 1997.
c) The use of pocket ionization chambers (i.e., pocket dosimeters) is subject to the following requirements:
d) Records of individual monitoring device (i.e., personnel dosimeter) results; records of daily pocket ionization chamber (i.e., pocket dosimeter) readings, records of estimates of exposures associated with off-scale pocket ionization chambers; and/or lost or damaged individual monitoring devices shall be kept for inspection by the Agency until the radioactive material license or certificate of registration is terminated.
e) Individual monitoring devices (i.e., personnel dosimeters) that require replacement shall be replaced at periods not to exceed one month. After replacement, each individual monitoring device shall be returned to the supplier for evaluation no later than 14 calendar days of the exchange date specified by the personnel monitoring supplier or as soon as practicable. In circumstances that make it impossible to return each individual monitoring device within the required time period, such circumstances shall be documented and available for review by the Agency.
f) If the individual monitoring device (i.e., personnel dosimeter) that is required by subsection (a) is lost or damaged, the worker shall cease work immediately until a replacement monitoring device meeting the requirements in subsection (a) is provided and the exposure is calculated for the time period from issuance to loss or damage of the individual monitoring device. The results of this calculated exposure and the time period for which the individual monitoring device was lost or damaged must be included in the records maintained in accordance with subsection (d).
g) In addition to other requirements of this Section, each individual performing radiography with sealed sources at a location other than a permanent radiography installation shall wear an alarm ratemeter. Each alarm ratemeter shall:
h) The alarm ratemeter shall be used in addition to, and not as a substitute for, the portable survey instrument required by Section 350.3030. The alarm ratemeter is intended to provide additional assurance that the radiation exposure levels are within regulatory limits.
