1.10.3.1.3

for dangerous goods of class 7, high consequence radioactive material is that with an activity equal to

or greater than a transport security threshold of 3 000 a2 per single package (see also 2.2.7.2.2.1)

except for the following radionuclides where the transport security threshold is given in table

1.10.3.1.3 below.
