35 Ill. Adm. Code 1000.302
Radioactive Emissions to Unrestricted Areas
Section 1000
Section 1000.302Â Radioactive
Emissions to Unrestricted Areas
a)Â Â Â Â Â Â Â Â A person must not possess, use, receive, or transfer licensed
material or engage in licensed activities in a way that releases to the air in
an unrestricted area radioactive material exceeding the concentration limits
specified in Appendix A. For this Section, concentrations of radioactive
material may be averaged over a period not greater than one year.
b)Â Â Â Â Â Â Â Â For this Section, the concentration limits in Appendix A apply
at the boundary of the restricted area. The concentration of radioactive
material discharged through a stack, pipe or similar conduit may be determined for
the point where the material leaves the conduit. If the conduit discharges
within the restricted area, the concentration at the boundary may be determined
by applying established factors for dilution, dispersion, or decay between the
point of discharge and the boundary.
