(1) Except as provided in subdivision (2), no
person shall receive, transfer, possess, manufacture, use, operate, store,
handle, transport or dispose of radioactive materials, or manufacture, use or
operate other sources of ionizing radiation, in such a manner as to cause any
employee to receive in any period of one calendar quarter, from radioactive
material and other sources of ionizing radiation, an occupational dose in
excess of the limits specified in the following table.

(2) An
employee can be permitted to receive an occupational dose to the whole body
greater than that permitted under subdivision (1) above, provided:
(A) During any calendar quarter the dose to
the whole body from radioactive material and other sources of radiation shall
not exceed three rem; and
(B) The
dose to the whole body when added to the accumulated occupational dose to the
whole body shall not exceed five (N-18) rem where "N" equals the individual's
age in years at his last birthday; and
(C) The individual's accumulated occupational
dose to the whole body has been determined on a clear and legible record. In
any case where it is not possible to obtain reports of the individual's
occupational dose for a previous complete calendar quarter in which the
individual received an occupational dose of radiation, it shall be assumed that
the individual has received the occupational dose specified in whichever of the
following columns apply:
|
Part of
Body |
Column 1
Assumed exposure in rem for calendar
quarters prior to January 1, 1961 |
Column 2
Assumed exposure in rem for calendar
quarters beginning on or after January 1, 1961 |
|
Whole body, gonads, active blood-forming organs, head
and trunk, lens of eye |

1 1/4 |
"Dose to the whole body" shall be deemed to include any dose to
the whole body, gonads, active blood-forming organs, head and trunk or lens of
eye.
(b)
(1) No
person shall receive, transfer, possess, manufacture, use, store, handle,
transport or dispose of radioactive material in such a manner as to cause any
employee to be exposed to airborne radioactive material in an average
concentration in excess of the limits specified in Appendix B, Table 1, Column
1, 10 CFR 20.
(2) The limits given
in Appendix B, Table 1, Column 1, 10 CFR 20 are based upon exposure to the
concentrations specified for forty hours in any period of seven consecutive
days. In any such period when the number of hours of exposure is less than
forty, the limits specified in the table may be increased proportionately. In
any such period where the number of hours of exposure is more than forty, the
limits specified in the table may be decreased proportionately.
(3) "Expose," as used in section
19-24-1 to
19-24-14,
inclusive, means that the individual is present in an airborne
concentration.
(4) No allowance
shall be made for use of protective clothing or equipment or particle size
except as specifically approved by the commissioner of environmental protection
or his representative.
(c)
(1) No
person shall receive, transfer, possess, manufacture, store, use, operate,
handle, transport or dispose of sources of ionizing radiation in such a manner
as to cause any employee who is under eighteen years of age to receive in any
period of one calendar quarter from radioactive material or other sources of
radiation an occupational dose in excess of ten per cent of the limits
specified in the table in subsection (a).
(2) No person shall receive, transfer,
possess, manufacture, store, use, operate, handle, transport or dispose of
sources of ionizing radiation in such a manner as to cause any employee who is
under eighteen years of age to be exposed to airborne radioactive material in
an average concentration in excess of the limits specified in Appendix B, Table
II, Column 1, 10 CFR 20. For the purpose of this section concentrations may be
averaged over periods not greater than one week.
(3) No allowance shall be made for use of
protective clothing or equipment or particle size except as specifically
approved by the department.
(d) No person shall receive, transfer,
possess, manufacture, use, operate, store, handle, transport or dispose of
sources of ionizing radiation in such a manner as to cause any individuals
other than employees to receive in any period of one calendar year from
radioactive materials or other sources of radiation a dose to the whole body in
excess of 0.5 rem (average 10 mrem/week).
(e) Nothing in sections
19-24-1 to
19-24-14,
inclusive, shall be interpreted as preventing intentional radiation exposure of
individuals for the purpose of diagnosis or therapy by persons licensed to
practice one or more of the healing arts within the authority granted to them
by the General Statutes.
