Or. Admin. R. 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. 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. 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.
