A radioactive material package must be accepted from the carrier at the time it is delivered. 
[10CFR20.1906(a)(1)] 

If a radioactive material package is to be held at the carrier's terminal for pickup, arrangements must 
be made to receive notification from the carrier of the arrival of the package at the time of arrival. The 
package must be picked up expeditiously upon receipt of notification (within three hours if 
practicable). [10CFR20.1906(c), Reg. Guide 7.3-5] 

Monitoring as described below must be performed as soon as practicable but at least within three 
hours if received during normal working hours or within three hours of the next work day if received 
after normal working hours. [10CFR20.1906] 

 
3.a  Upon receipt of a package of radioactive material, the package shall be placed in a restricted area. 

Assure appropriate personnel are notified. 

 

3.b Survey the entire exterior surface of the package at the time of receipt and assure that the maximum 

radiation level does not exceed 2 mSv/hr (200 mRem/hr). Survey all sides of the device at 1m from 
the exterior surfaces of the packages and assure that the maximum radiation level does not exceed 
0.1 mSv/hr (10 mRem/hr). If either of these limits are exceeded, notify the Radiation Safety Officer 
immediately. Record the maximum radiation levels measured at the package surface and at 1m from 
the package surface on the Receiving Report. [10CFR20.1906(d), 10CFR71.47] 

 
Note:  If any of these limits are exceeded, the Radiation Safety Officer must immediately notify 

Inspect the package for any evidence of physical damage. Record the results of this inspection on the 
Receiving Report. Also record on the Receiving Report the date, source model number, source serial 
number, radionuclide, activity, the individuals name making the record, transport package model 
number, mass or activity of the depleted uranium and the package serial number. [10CFR34.63] 

Assure that the package is locked or place the package into an outer locked container and secure the 
package in accordance with your license requirements. [10CFR34.35, 10CFR34.23] 

Keep a copy of the Operating Manual for the package on file to assure you have the proper opening 
and handling instructions. Assure that the instructions are followed and any noted special precautions 
are performed. [10CFR20.1906(e)]
