Article 35 - RADIATION
Section 28-35-135n - Definitions
Current through Register Vol. 43, No. 52, December 26, 2024
As used in these regulations, each of the following terms shall have the meaning specified in this regulation:
(a)"NARM" means any naturally occurring or accelerator-produced radioactive material, not including by-product, source, or special nuclear material.
(b)"Nationally tracked source" means a sealed source containing any quantity of radioactive material equal to or greater than any threshold listed in the table in this subsection. For purposes of the definition of nationally tracked source," sealed source" shall be defined as radioactive material that is sealed in a capsule or closely bonded, that is in a solid form, and that is not exempt from regulatory control. For purposes of the definition of"nationally tracked source,""sealed source" shall not include any radioactive material encapsulated solely for disposal and any nuclear material contained in any fuel assembly, subassembly, fuel rod, or fuel pellet. Category I nationally tracked sources contain radioactive material in quantities equal to or greater than the category 1 threshold. Category 2 nationally tracked sources contain radioactive material in quantities equal to or greater than the category 2 threshold but less than the category 1 threshold.

* The Terabecquerel (TBq) values are the regulatory standard.
** The curie (Ci) values specified are obtained by converting from the TBq value. The curie values are provided for practical usefulness and are rounded after conversion.
(c)"Natural radioactivity" means the radioactivity of naturally occurring nuclides.
(d)"Non-fixed contamination" means contamination that can be removed from a surface during normal conditions of transport.
(e)"Nonionizing radiation" means radiation not capable of producing ionization, including sound and radio waves and visible, infrared, or ultraviolet light.
(f)"Non-stochastic effect" means a health effect, the severity of which varies with the dose and for which a threshold is believed to exist. For purposes of these regulations,"deterministic effect" shall be considered an equivalent term.
(g)"Normal operating procedures" means operating procedures for conditions suitable for routine purposes with shielding and barriers in place, including routine alignment procedures. This term shall not include maintenance procedures and routine and emergency radiation safety considerations.
(h)"Normal treatment distance" means either of the following:
(i)"Nuclear regulatory commission,""NRC," and commission" mean the U.S. nuclear regulatory commission or its authorized representatives.
(j)"NVLAP" means the national voluntary laboratory accreditation program.
