Radioactive marker means radioactive material placed subsurface or on a structure intended for subsurface use for the purpose of depth determination or direction orientation.
Radioactive waste means any waste which contains radioactive material in concentrations which exceed those listed in 10 CFR Part 20, Appendix B, Table II, Column 2.
Radioactivity means the transformation of unstable atomic nuclei by the emission of radiation.
Airborne radioactivity area means a room, enclosure, or area in which airborne radioactive materials, composed wholly or partly of licensed material, exist in concentrations:
Natural radioactivity means radioactivity of naturally occurring nuclides.
Radioactive material means any solid, liquid, or gas which emits radiation spontaneously.
Airborne radioactive material means any radioactive material dispersed in the air in the form of dusts, fumes, particulates, mists, vapors, or gases.
Low-level radioactive waste or “waste” means radioactive material that consists of or contains class A, B, or C radioactive waste as defined by 10 C.F.R. 61.55, as in effect on January 26, 1983, but does not include waste or material that is any of the following:
Radioactive substance means a substance that emits ionizing
Residual radioactivity means radioactivity in structures, materials, soils, groundwater, and other media at a site resulting from activities under the licensee's control. This includes radioactivity from all licensed and unlicensed sources used by the licensee, but excludes background radiation. It also includes radioactive materials remaining at the site as a result of routine or accidental releases of radioactive materials at the site and previous burials at the site, even if those burials were made in accordance with the provisions of Part IV (12VAC5-481-600 et seq.) of this chapter.
explosive actuated fastening device means a tool that is activated by an explosive charge and that is used for driving bolts, nails and similar objects for the purpose of providing fixing;
Carcinogen means a chemical that causes an increased incidence of benign or malignant neoplasms, or a substantial decrease in the latency period between exposure and onset of neoplasms through oral or dermal exposure, or through inhalation exposure when the cancer occurs at nonrespiratory sites in at least one (1) mammalian species or man through epidemiological studies or clinical studies, or both.
Corrosive means any substance that when it comes in contact
Explosive means a chemical compound, device, or mixture:
Special form radioactive material means radioactive material that satisfies the following conditions:
Semisolid means a product that, at room temperature, will not pour, but will spread or deform easily, including but not limited to gels, pastes, and greases.
Polychlorinated biphenyls means aromatic compounds formed in such a manner that the hydrogen atoms on the biphenyl molecule (two benzene rings bonded together by a single carbon-carbon bond) may be replaced by up to ten chlorine atoms; and
Flammable means a chemical that falls into one of the following categories:
Normal form radioactive material means radioactive material that has not been demonstrated to qualify as special form radioactive material.
Hydrofluorocarbons means compounds that only contain hydrogen, fluorine, and carbon.
Radioactive Products or Waste means any radioactive material produced in, or any material made radioactive by exposure to the radiation incidental to the production or utilization of nuclear fuel, but does not include radioisotopes which have reached the final stage of fabrication so as to be usable for any scientific, medical, agricultural, commercial or industrial purpose.
Chemical agent shall mean any compound which, when suitably disseminated, produces incapacitating, damaging or lethal effects on people, animals, plants or material property.
Explosives (1) means solid, liquid or gaseous substances or mixtures of substances which, in their application as primary, booster, or main charges in warheads, demolition and other applications, are required to detonate.
Friable asbestos material means any material that contains more than 1% asbestos by weight and that can be crumbled, pulverized, or reduced to powder when dry, by hand pressure.
PCBs means polychlorinated biphenyls.
