Current through Register Vol. 40, No. 24, July 15, 2024
A. Any licensee
					 who possesses or uses an aggregated quantity of Category 1 or Category 2
					 radioactive material equal to or in excess of those in subdivision 1 of this
					 subsection shall establish a physical protection program that meets all

Combinations of radioactive materials listed in
								  this table3
See footnote 4
1The aggregate
								  activity of multiple, collocated sources of the same radionuclides should be
								  included when the total activity equals or exceeds the Category 1 or Category 2
								  threshold.
2The primary values
								  used for compliance are TBq. The curie (Ci) values are rounded to two
								  significant figures for informational purposes only.
3Radioactive materials
								  are to be considered aggregated or collocated if breaching a common physical
								  barrier (e.g., a locked door at the entrance to a storage room) would allow
								  access to the radioactive material or devices containing the radioactive
								  material.
4If several
								  radionuclides are aggregated, the sum of the ratios of the activity of each
								  source, i of radionuclide, n, A (i,n), to the Category 1 or Category 2
								  threshold for radionuclide n, Qn, listed for that
								  radionuclide equals or exceeds one. (aggregated source activity for
								  radionuclide A) / (quantities of concern for radionuclide A) + (aggregated
								  source activity for radionuclide B) / (quantities of concern for radionuclide
								  B) + etc... >=1.
2. A licensee that possesses radioactive
					 waste that contains Category 1 or Category 2 quantities of radioactive material
					 is exempt from the 0requirements of this section.
3. A licensee that possesses radioactive
					 waste that contains discrete sources, ion-exchange resins, or activated
					 material that weighs less than 2,000 kg (4,409 lbs) is not exempt from the
					 requirements of this section. The licensee shall implement the following
					 requirements to secure the radioactive waste:
a. Use continuous physical barriers that
					 allow access to the radioactive waste only through established access control
					 points;
b. Use a locked door or
					 gate with monitored alarm at the access control point;
c. Assess and respond to each actual or
					 attempted unauthorized access to determine whether an actual or attempted
					 theft, sabotage, or diversion occurred; and
d. Immediately notify the local
					 law-enforcement agency (LLEA) and request an armed response from the LLEA upon
					 determination that there was an actual or attempted theft, sabotage, or
					 diversion of the radioactive waste.
