Ohio Admin. Code 3701:1-38-13 - Dose limits for individual members of the public
(A) Each licensee or registrant shall conduct
operations so that:
(1) The total effective
dose equivalent to individual members of the public from the licensed or
registered operation does not exceed one millisievert (0.1 rem) in a year,
exclusive of the dose contribution from the following:
(a) Background radiation;
(b) Radiation attributable to any medical
administration the individual has received;
(c) Exposure to an individual that was
administered radioactive materials and has been released in accordance with
rule
3701:1-58-30
of the Administrative Code or equivalent United States nuclear regulatory
agency or agreement state regulations;
(d) Voluntary participation in medical
research programs;
(e) The
licensee's disposal of radioactive material into sanitary sewerage in
accordance with paragraph (D) of rule
3701:1-38-19 of
the Administrative Code; and
(2) The dose in any unrestricted area from
external sources, exclusive of the dose contribution from patients administered
radioactive material and released in accordance with rule
3701:1-58-30
of the Administrative Code or equivalent United States nuclear regulatory
agency or agreement state regulations, does not exceed 0.02 millisievert (0.002
rem) in any one hour.
(B) If the licensee or registrant permits
members of the public to have access to controlled or restricted areas, the
limits for members of the public continue to apply to those
individuals.
(C) A licensee,
registrant, or an applicant for a license or registration may apply for prior
department authorization to operate up to an annual dose limit for an
individual member of the public of five millisievert (0.5 rem). This
application shall include the following information:
(1) Demonstration of the need for and the
expected duration of operation in excess of the limit set forth in paragraph
(A) of this rule;
(2) The
licensee's or registrant's program to assess and control dose within the five
millisievert (0.5 rem) annual limit; and
(3) The procedures that the registrant or
licensee will follow to maintain the dose ALARA.
(4) Notwithstanding paragraph (A)(1) of this
rule, a licensee may permit visitors to an individual who cannot be released,
under rule
3701:1-58-30
of the Administrative Code, to receive a radiation dose greater than one
millisievert (0.1 rem) if:
(a) The radiation
dose received does not exceed five millisievert (0.5 rem); and
(b) The authorized user, as defined in
Chapter 3701:1-58 of the Administrative Code, has determined before the visit
that it is appropriate.
(D) In addition to the requirements of
paragraphs (A) and (B) of this rule:
(1) A
licensee subject to the provisions of the United States environmental
protection agency's generally applicable environmental radiation standards in
40 C.F.R. 190
, as published in the July 1, 2014 Code
of Federal Regulations
(as in effect on the
effective date of this rule) , shall also comply with those
standards.
(2) The department may
impose additional restrictions on radiation levels in unrestricted areas and on
the total quantity of radionuclides that a licensee may release in effluents in
order to restrict the collective dose.
(E) The licensee or registrant shall
demonstrate compliance with dose limits for individual members of the public.
(1) The licensee or registrant shall make or
cause to be made surveys of radiation levels in unrestricted and controlled
areas and radioactive materials in effluents released to unrestricted and
controlled areas to demonstrate compliance with the dose limits for individual
members of the public in paragraph (A) of this rule.
(2) A licensee or registrant shall show
compliance with the annual dose limit in paragraph (A) of this rule by:
(a) Demonstrating by measurement or
calculation that the total effective dose equivalent to the individual likely
to receive the highest dose from the licensed or registered operation does not
exceed the annual dose limit; or
(b) Demonstrating that:
(i) The annual average concentrations of
radioactive material released in gaseous and liquid effluents at the boundary
of the unrestricted area do not exceed the values specified in appendix C to
rule
3701:1-38-12
of the Administrative Code; and
(ii) If an individual were continuously
present in an unrestricted area, the dose from external sources would not
exceed 0.02 millisievert (0.002 rem) in an hour and 0.5 millisievert (0.05 rem)
in a year.
(3) Upon approval from the department, the
licensee may adjust the effluent concentration values in appendix C to rule
3701:1-38-12
of the Administrative Code for members of the public, to take into account the
actual physical and chemical characteristics of the effluents, such as aerosol
size distribution, solubility, density, radioactive decay equilibrium, or
chemical form.
