bThe values of A1 and A2 in curies (Ci) are approximate and for information only; the regulatory standard units are Terabecquerels (TBq). See part 4731.0423, subpart 1 - Determination of A1 and A2.

cThe activity of Ir-192 in special form may be determined from a measurement of the rate of decay or a measurement of the radiation level at a prescribed distance from the source.

dThese values apply only to compounds of uranium that take the chemical form of UF6, UO2F2, and UO2(NO3)2 in both normal and accident conditions of transport.

eThese values apply only to compounds of uranium that take the chemical form of UO3, UF4, and UCl4 and hexavalent compounds in both normal and accident conditions of transport.

fThese values apply to all compounds of uranium other than those specified in notes d and e.

gThese values apply to unirradiated uranium only.

hA2 = 0.74 TBq (20 Ci) for Mo-99 for domestic use.

Subp. 2. Specific activity. This subpart specifies specific activity for individual radionuclides.
