aA1 and/or A2 values for these parent radionuclides include contributions from daughter nuclides with half-lives less than 10 days as listed in footnote (a) to Table 2 in the "IAEA Regulations for the Safe Transport of Radioactive Material, SSR-6" (IBR, see §171.7 of this subchapter).

bThe values of A1 and A2 in curies (Ci) are approximate and for information only; the regulatory standard units are Terabecquerels (TBq), (see §171.10).

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, 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) of this table.

gThese values apply to unirradiated uranium only.

h[Reserved]

iA2 = 0.74 TBq (20 Ci) for Mo-99 for domestic use.
