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 |

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.Conn.
