Section 61-63.IX.RHA 9.3 - Exemptions
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.
