Sec. 35.92  Decay-in-storage.

    (a) A licensee may hold byproduct material with a physical half-life 
of less than 65 days for decay-in-storage before disposal in ordinary 
trash and is exempt from the requirements of Sec. 20.2001 of this 
chapter if it:
    (1) Holds byproduct material for decay a minimum of ten half-lives;
    (2) Monitors byproduct 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 meter 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 it has decayed to 
background radiation level before disposal.
    (b) A licensee shall retain a record of each disposal permitted 
under paragraph (a) of this section for three years. The record must 
include the date of the disposal, the date on which the byproduct 
material was placed in storage, the radionuclides disposed, the survey 
instrument used, the background dose rate, the dose rate measured at the 
surface of each waste container, and the name of the individual who 
performed the disposal.
