3. 10 mSv/hr (1000 mR/hr)

The maximum radiation exposure rate at the surface of an unbroken radioactive material package may be at most 10 mSv/hr (1000 mR/hr).


Explanation:

The labels of radioactive package also list the type of radioactive nuclide and the amount of activity. This additional information help in determining the level of risk involved while shipping.

'Exclusive use shipment' can be used to send a package with a maximum dose rate of 10 mSv/hr if special requirements and instructions are followed.

The level of radiation exposure at the surface of an unbroken package should not exceed 1,000 mR/hr in any cases.
