Three types of lead containers are at present used in the Danish AEC packagings for radioactive material: open type (5 and 10 mm), semi-closed type (20 and 30 mm) and closed type (45, 60, 80, and 100 mm). The opentype containers are used in tin cans as containment vessels in cardboard packagings. The others are used in the wooden packagings. The closedtype lead containers can be made leaktight and then used as containment vessels. Suitable methods for that purpose that have been tested and proved satisfactory are described. Radiation-shielding properties of the lead containers are discussed and a description of the evaluation of those properties given. Equipment and procedure for radiation leakage testing by the autoradiographic and radiometric method are described, and the test findings are discussed. Conclusions are drawn regarding the future use of all types of lead containers, and suggestions are made for extension of the open-type series, discutinuation of the use of the semi-closed series and extension of the closed-type series after it has been made leaktight.
