Section 11-45-153 - Decay-in-storage(a) A licensee shall hold radioactive material for decay-in-storage before disposal in ordinary trash and is exempt from the waste disposal requirements of subchapter 4 if the licensee: (1) Holds radioactive material for decay a minimum of ten half-lives;(2) Monitors radioactive material at the container surface before disposal as ordinary trash and determines that its radioactivity cannot be distinguished from the background radiation level with a radiation detection survey instrument set on its most sensitive scale and with no interposed shielding;(3) Removes or obliterates all radiation labels; and(4) Separates and monitors each generator column individually with all radiation shielding removed to ensure that its contents have decayed to background radiation level before disposal.(b) For radioactive material disposed in accordance with subsection (a), the licensee shall retain a record of each disposal. The record shall include the date of the disposal, the date on which the radioactive material was placed in storage, the radionuclides disposed, the model and serial number of the survey instrument used, the background dose rate, the radiation dose rate measured at the surface of each waste container, and the name of the individual who performed the disposal.[Eff 11/12/99] (Auth: HRS §§ 321-10, 321-11, 321-71) (Imp: HRS §§ 321-1, 321-11(21), 321-71)
