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 radioactive material, exist in concentrations:
Natural radioactivity means radioactivity of naturally occurring nuclides.
Corrosive means any substance that when it comes in contact
Reactivate or “reactivation” means the process as outlined in rule 645—21.16(17A,147,272C) by which an inactive license is restored to active status.
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.
Reactivation means the process whereby an inactive licensee obtains a current license.
Acute toxicity means concurrent and delayed adverse effects that result from an acute exposure and occur within any short observation period, which begins when the exposure begins, may extend beyond the exposure period, and usually does not constitute a substantial portion of the life span of the organism.
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.
Biological agent shall mean any pathogenic (disease producing) micro-organism(s) and/or biologically produced toxin(s) (including genetically modified organisms and chemically synthesized toxins) which cause illness and/or death in humans, animals or plants.
Radionuclide means a radioactive element or a radioactive isotope.
Radioactive marker means radioactive material placed subsurface or on a structure intended for subsurface use for the purpose of depth determination or direction orientation.
Explosive means a chemical compound, device, or mixture:
Airborne radioactive material means any radioactive material dispersed in the air in the form of dusts, fumes, particulates, mists, vapors, or gases.
Chemical agent shall mean any compound which, when suitably disseminated, produces incapacitating, damaging or lethal effects on people, animals, plants or material property.
Fungus means any type or form of fungus, including mold or mildew, and any mycotoxins, spores, scents or by-products produced or released by fungi.
Substances means chemical elements and their compounds in the natural state or obtained by any production process, including any additive necessary to preserve the stability of the products and any impurity deriving from the process used, but excluding any solvent which may be separated without affecting the stability of the substance or changing its composition;
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 utilisation 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.
Radioactive material means any solid, liquid, or gas which emits radiation spontaneously.
Pathological waste means waste material consisting of only human or animal remains, anatomical parts, and/or tissue, the bags/containers used to collect and transport the waste material, and animal bedding (if applicable).
Flammable means a chemical that falls into one of the following categories:
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.
Dangerous weapon means any weapon, device, instrument, material, or substance, animate or inanimate, which under the circumstances in which it is used, attempted to be used, or threatened to be used is readily capable of causing death or serious physical injury.
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.
Activity means the rate of disintegration or transformation or decay of radioactive material. The units of activity are the becquerel (Bq) and the curie (Ci).
Odor means that property of an air contaminant that affects the sense of smell.
