64E-5.624. Decay in Storage

(1) A licensee shall hold radioactive material with a physical half life of less than 120 days for decay in storage before disposal as ordinary trash. A licensee is exempt from the requirements of paragraph 64E-5.331(1)(c), F.A.C., of these regulations if:

(a) The radioactive material is held for decay a minimum of 10 half-lives;

(b) The radioactive material is monitored at the container surface before disposal as ordinary trash and its radioactivity cannot be distinguished from the background radiation level in a low background radiation area with a radiation survey instrument set on its most sensitive scale and with no interposed shielding;

(c) All radiation labels are removed or obliterated; and

(d) Each generator column is separated and monitored individually with all radiation shielding removed to ensure that its contents have decayed to background radiation levels before disposal.

(2) The licensee shall retain a record of each disposal for 3 years. The record shall include:

(a) The date of the disposal;

(b) The date on which the radioactive material was placed in storage;

(c) The radionuclides disposed;
