OAR 333-116-0250
Surveys for Contamination and Ambient Radiation Dose Rate
(1)
A licensee must survey with an appropriate radiation detection survey instrument, at the end of each day of use, all areas where radiopharmaceuticals are routinely prepared for use or administered. Radiation surveys are not required in areas where patients or human research subjects are confined when they cannot be released under OAR 333-116-0260 (Release of Patients Containing Therapeutic Quantities of Byproduct material or Permanent Implants). Radiation surveys are required when patients receive a therapeutic dose or brachytherapy implant and prior to release.(2)
A licensee must survey with an appropriate radiation detection survey instrument at least once each week all areas where radiopharmaceuticals or radioactive wastes are stored.(3)
A licensee must conduct the surveys required by section (1) and (2) of this rule so as to be able to measure dose rates as low as 1 uSv (0.1 mrem) per hour.(4)
A licensee must establish dose rate action levels for the surveys required by sections (1) and (2) of this rule and must require that the individual performing the survey immediately notify the Radiation Safety Officer if a dose rate exceeds an action level.(5)
A licensee must survey for removable contamination each day of use all areas where radiopharmaceuticals are routinely prepared for use or administered and each week where radioactive materials are stored.(6)
A licensee must conduct the surveys required by section (5) of this rule so as to be able to detect contamination on each wipe sample of 33.3 Bq (2000 dpm).(7)
A licensee must establish removable contamination action levels for the surveys required by section (5) of this rule and must require that the individual performing the survey immediately notify the Radiation Safety Officer if contamination exceeds action levels.(8)
A licensee must retain a record of each survey required by this rule in accordance with OAR 333-100-0057 (Maintenance of Records). The record must include the date of the survey, a sketch of each area surveyed, action levels established for each area, the measured dose rate at several points in each area expressed in Sv mrem per hour or the removable contamination in each area expressed in Bq (dpm) per 100 square centimeters, the serial number and the model number of the instrument used to make the survey or analyze the samples and the initials of the individual who performed the survey.
