Universal Citation: SC Code Regs 61-63.IX.RHA 9.3
Current through Register Vol. 48, No. 9, September 27, 2024
9.3.1 Persons who receive, possess, use, process, transfer, transport, store, and/or commercially distribute NORM are exempt from the requirements of the provisions of this part if the materials contain, or are contaminated at, concentrations of:
9.3.1.1 Thirty
(30) picocuries per gram or less of TENR due to radium 226 or radium 228 in soil,
averaged over any 100 square meters and averaged over the first 15 centimeters of
soil below the surface, provided the radon emanation rate is less than 20 picocuries
per square meter per second.
9.3.1.2
Thirty (30) picocuries per gram or less of TENR due to radium 226 or radium 228 in
media other than soil, provided the radon emanation rate is less than 20 picocuries
per square meter per second; or
9.3.1.3
Five (5) picocuries per gram or less of TENR due to radium 226 or radium 228 in
soil, averaged over any 100 square meters and averaged over the first 15 centimeters
of soil below the surface, in which the radon emanation rate is equal to or greater
than 20 picocuries per square meter per second,
9.3.1.4 Five (5) picocuries per gram or less of
TENR due to radium 226 or radium 228 in media other than soil, in which the radon
emanation rate is equal to or greater than 20 picocuries per square meter per
second; or
9.3.1.5 One hundred fifty
(150) picocuries or less per gram of any other NORM radionuclide in soil, averaged
over any 100 square meters and averaged over the first 15 centimeters of soil below
the surface,
9.3.1.6 One hundred fifty
(150) picocuries or less per gram of any other NORM radionuclide in media other than
soil;
9.3.1.7 Materials in the recycling
process contaminated with scale or residue not otherwise exempted, and other
equipment containing NORM are exempt from the requirements of these rules if the
maximum radiation exposure level does not exceed 50 microroentgens per hour
including the background radiation level at any accessible point; or
9.3.2 Persons who possess facilities, equipment or land contaminated with NORM in quantities less than the following levels are exempt from the requirements of the provisions of this part:
9.3.2.1 Surface contamination which averages 5000
disintegrations per minute per 100 centimeters squared over the entire measured
surface;
9.3.2.2 Not to exceed a maximum
reading of 15000 disintegrations per minute per 100 centimeters squared to an area
of not more than 100 centimeters squared, notwithstanding the maximum aforementioned
limit. The maximum radiation exposure level shall not exceed the limit specified in
RHA 9.3.1.7; or
9.3.2.3 Removable
contamination not to exceed 1000 disintegrations per minute per 100 centimeters
squared.
