Ohio Administrative Code
Title 3701:1 - Radiation Control
Chapter 3701:1-38 - General Radiation Protection Standards for Sources of Radiation
Section 3701:1-38-14 - Survey and monitoring requirements
Universal Citation: OH Admin Code 3701:1-38-14
Current through all regulations passed and filed through March 18, 2024
(A) Each licensee or registrant shall:
(1) Make, or cause to be made, surveys of
areas, including the subsurface, that are:
(a) Necessary to comply with this chapter:
and
(b) Reasonable under the
circumstances to evaluate:
(i) Radiation
levels;
(ii) Concentrations or
quantities of residual radioactivity; and
(iii) The potential radiological hazards of
the radiation levels and residual radioactivity detected.
(2) Notwithstanding paragraph (C)
of rule
3701:1-38-20 of the
Administrative Code, records from surveys describing the location and amount of
subsurface residual radioactivity identified at the site must be kept with
records important for decommissioning, and such records must be retained in
accordance with paragraph (I) of rule
3701:1-40-17,
paragraph (F) of rule
3701:1-44-18,
and paragraph (D) of rule
3701:1-56-19
of the Administrative Code, as applicable.
(3) Ensure that instruments and equipment
used for quantitative radiation measurements, such as dose rate and effluent
monitoring, are calibrated annually for the radiation measured, except as
otherwise specified in Chapter 3748. of the Revised Code, rules adopted
thereunder, or a license condition.
(4) Ensure that all personnel dosimeters,
except for direct and indirect reading dosimeters used to measure the dose to
any extremity, that require processing to determine the radiation dose and that
are used to comply with paragraph (A) of rule
3701:1-38-12
of the Administrative Code, with other applicable provisions of these
regulations, or with conditions specified in a license or registration shall be
processed and evaluated by a dosimetry processor that:
(a) Holds a current personnel dosimetry
accreditation from the national voluntary laboratory accreditation program of
the national institute of standards and technology; and
(b) Is approved in this accreditation process
for the type of radiation or radiations included in the national voluntary
laboratory accreditation program that most closely approximates the type of
radiation or radiations for which the individual wearing the dosimeter is
monitored; and
(5) Have
procedures in place to minimize the likelihood of a deceptive exposure of an
individual monitoring device, and in the event of a suspected deceptive
exposure, an investigation should be conducted by the radiation safety officer
for licensees or individual responsible for radiation
protection for registrants which will lead to corrective action as
necessary.
(B) Conditions requiring individual monitoring of external and internal occupational dose are as follows:
(1) Each
licensee or registrant shall monitor exposures from sources of radiation at
levels sufficient to demonstrate compliance with the occupational dose limits
of rule
3701:1-38-12
of the Administrative Code. Each licensee or registrant shall monitor
occupational exposure to radiation from sources of radiation under the control
of the licensee or registrant and shall supply and require the use of
individual monitoring devices by:
(a) Adults
likely to receive, in one year from sources of radiation external to the body,
a dose in excess of ten per cent of the limits in paragraph (A) of rule
3701:1-38-12
of the Administrative Code;
(b)
Minors likely to receive, in one year, from radiation sources external to the
body, a deep dose equivalent in excess of one millisievert ( 0.1 rem), a lens
dose equivalent in excess of 1.5 millisievert ( 0.15 rem), or a shallow dose
equivalent to the skin or to the extremities in excess of five millisievert (
0.5 rem);
(c) Declared pregnant
women likely to receive during the entire pregnancy, from radiation sources
external to the body, a deep dose equivalent in excess of one millisievert (
0.1 rem); and
(d) Individuals
entering a high or very high radiation area.
(2) To determine compliance with paragraph
(D) of rule
3701:1-38-12
of the Administrative Code, each licensee shall monitor the occupational intake
of radioactive material by and assess the committed effective dose equivalent
to:
(a) Adults likely to receive, in one
year, an intake in excess of ten per cent of the applicable ALI in appendix C
to rule
3701:1-38-12
of the Administrative Code;
(b)
Minors likely to receive, in one year, a committed effective dose equivalent in
excess of one millisievert ( 0.1 rem); and
(c) Declared pregnant women likely to
receive, during the entire pregnancy, a committed effective dose equivalent in
excess of one millisievert ( 0.1 rem).
(C) Each licensee or registrant shall ensure that any individual who is required to monitor occupational doses in accordance with paragraph (B)(1) of this rule wears an individual monitoring device as follows:
(1) An individual monitoring device,
used for monitoring the dose to the whole body, shall be worn at the unshielded
location of the whole body likely to receive the highest exposure. When a
protective apron is worn, the location of the individual monitoring device is
typically at the neck.
(2) An
individual monitoring device, used for monitoring the dose to an embryo or
fetus of a declared pregnant woman pursuant to paragraph (H) of rule
3701:1-38-12
of the Administrative Code, shall be located at the waist under any protective
apron being worn by the woman.
(3)
An individual monitoring device, used for monitoring the lens dose equivalent,
to demonstrate compliance with paragraph (A) of rule
3701:1-38-12
of the Administrative Code, shall be located at the neck outside any protective
apron being worn by the monitored individual, or at an unshielded location
close to the eye.
(4) An individual
monitoring device, used for monitoring the dose to the extremities, to
demonstrate compliance with paragraph (A)(2) of rule
3701:1-38-12
of the Administrative Code, shall be worn on the extremity likely to receive
the highest exposure. Each individual monitoring device shall be oriented to
measure the highest dose to the extremity being monitored.
(5) When only one individual monitoring
device is used to determine the effective dose equivalent for external
radiation pursuant to paragraph (A)(4)(b) of rule
3701:1-38-12
of the Administrative Code, it shall be located at the neck outside the
protective apron. When a second individual monitoring device is used for the
same purpose, it shall be located under the protective apron at the waist. The
second individual monitoring device is required for a declared pregnant
woman.
