Abstract
The paper describes the design of a radioisotope container and the method used for calculation of the shield dimensions necessary to bring down the surface radiation dose to a desired level. Two such containers were fabricated, each to handle 25 Ci of scandium-46 sand in 16 glass ampoules. Since the containers were also to be used for transportation of the activity over 1000 miles by road [1] the ampoule housing was felt-lined to absorb shocks.
