the design for low dispersible radioactive material shall require multilateral approval. low
dispersible radioactive material shall be such that the total amount of this radioactive material in a
package, taking into account the provisions of 6.4.8.14, shall meet the following requirements:
(a) the radiation level at 3 m from the unshielded radioactive material does not exceed 10 msv/h;
(b) if subjected to the tests specified in 6.4.20.3 and 6.4.20.4, the airborne release in gaseous and
particulate forms of up to 100 μm aerodynamic equivalent diameter would not exceed 100 a2.
a separate specimen may be used for each test; and
(c) if subjected to the test specified in 2.2.7.2.3.1.4 the activity in the water would not exceed
100 a2. in the application of this test, the damaging effects of the tests specified in (b) above
shall be taken into account.
