The licensee shall establish and submit for department
approval a contamination control program to limit the spread of unsealed
sources of radioactive materials. This program shall include contamination
action levels, corresponding actions taken if these levels are exceeded,
frequency of measurement and maintenance of records.
(1) Unless otherwise specified in the
license, the licensee shall perform the following:
(a) A survey with a radiation survey
instrument shall be completed at the end of each day of use or receipt of all
areas where radioactive materials are used or received.
(b) A weekly survey with a radiation survey
instrument shall be completed of all areas where radioactive materials or
radioactive waste are stored.
(c) A
wipe survey shall be completed for removable contamination weekly during weeks
of use of all areas where radioactive materials or waste are routinely used or
stored.
(d) Surveys required by
paragraphs (1)(a), (b) and (f), of this rule, shall be completed with an
instrument capable of measuring dose rates as low as 0.1 millirem (1 µSv)
per hour, if applicable.
(e) A wipe
survey shall be completed for removable contamination at the end of each day of
use of all areas where radioactive materials are routinely used if the
radioactive materials authorized by the license are not detectable with
instruments described in paragraph (1)(d), above.
(f) Monitoring shall be performed of
individuals for contamination prior to leaving the restricted area.
(g) The radiation safety officer shall be
notified if the contamination detected during the surveys required by this rule
exceeds the action levels specified in subsection (2),
below.
(2) Unless
otherwise specified in the license, the licensee shall take the following
actions if the corresponding action levels are exceeded:
(a) Follow decontamination procedures and
resurvey to determine effectiveness of decontamination efforts if the action
levels are exceeded when conducting surveys described in paragraph (1)(a), (b)
or (f), above;
(b) Follow emergency
procedures if the radiation detected during the survey required in paragraph
(1)(f), of this rule, is above action levels; and,
(c) Follow decontamination procedures and
resurvey to determine effectiveness of decontamination efforts if the action
levels listed below are exceeded for the survey required in paragraph (1)(c) or
(e), above;
1. 100 dpm per 100 square
centimeters of any alpha-emitting radioactive materials not listed in this
section,
2. 1, 000 dpm per 100
square centimeters of any beta- or gamma-emitting radioactive materials not
listed in this section,
3. 50 dpm
per 100 square centimeters of any transuranic,
4. 2, 000 dpm per 100 square centimeters of
any uranium, or
5. 2, 000 dpm per
100 square centimeters of any radioactive material with a half-life of less
than 80 hours.
(3) The licensee shall retain a record of
each survey required by this section for 3 years. These records shall include:
(a) The date of the survey;
(b) An annotated diagram of each area
surveyed;
(c) Background
levels;
(d) Measured dose rates,
keyed to the diagram, expressed in millirem (microsieverts) per hour or the
removable contamination, keyed to the diagram, expressed in dpm per 100 square
centimeters, or counts per minute if performed with a radiation survey
instrument, with the action level described in paragraph (2)(a), of this
rule;
(e) The serial number and
model number of the instrument used to make the survey or analyze the samples;
and,
(f) The initials of the person
who performed the survey.
(4) Records of surveys described in paragraph
(1)(f), need not be recorded unless the action level described in paragraph
(2)(a), of this rule is exceeded.
