Current through Register Vol. 48, No. 38, September 20, 2024
a) Each licensee or registrant shall conduct
operations so that:
1) The dose in any
unrestricted area from external sources, exclusive of the dose contributions
from patients administered radioactive material and released in accordance with
32 Ill. Adm. Code 335, does not exceed 0.02 mSv (0.002 rem) in any one hour;
and
2) The total effective dose
equivalent to individual members of the public from a radiation machine does
not exceed:
A) 5 mSv (0.5 rem) in any year at
any location within a facility where a radiation machine was installed before
January 1, 1994, and the use of the radiation machine does not change on or
after January 1, 1994; or
B) 1 mSv
(0.1 rem) in any year at any location within a facility where a radiation
machine is installed or where the radiation machine or its use changes on or
after January 1, 1994.
AGENCY NOTE: It is the Agency's intent to allow registrants
using radiation machines in facilities designed to the 5 mSv (0.5 rem) limit to
continue to use the 5 mSv (0.5 rem) total effective dose equivalent limit for a
member of the public. This includes locations where the intensity of the
radiation machine is not increased beyond the design basis, the type of
radiation machine use is not changed and the type of facility use is not
changed; or
3)
The total effective dose equivalent to individual members of the public from a
licensed operation does not exceed 1 mSv (0.1 rem) in any year, exclusive of
the dose contribution from:
A) Background
radiation;
B) Any medical
administration the individual has received;
C) Exposure to individuals administered
radioactive material and released in accordance with 32 Ill. Adm. Code
335;
D) Voluntary participation in
medical research programs; and
E) A
licensee's disposal of radioactive material into sanitary sewerage in
accordance with Section
340.1030
of this Part.
b) A licensee may apply for prior Agency
authorization to operate up to an annual dose limit for an individual member of
the public of 5 mSv (0.5 rem). This application shall include the following
information:
1) Demonstration of the need for
and the expected duration of operations in excess of the limit in subsection
(a)(3) of this Section;
2) The
licensee's or registrant's program to assess and control dose within the 5 mSv
(0.5 rem) annual limit; and
3) The
procedures to be followed to maintain the dose ALARA.
c) Prior to allowing a member of the public
to enter a restricted area, the licensee or registrant shall give instructions
on radiation hazards and protective measures to that individual.
