The conventional means employed for shielding the skin from roentgen rays is lead foil or rubberized lead sheet. When small areas of the skin are treated with intensive doses, the protection of the remaining areas has to be very accurate. The cutting of those materials to an exact size is time consuming and often difficult. If a shield is too large or cannot be corrected in form, another one has to be made.

Rubberized lead and lead foil are stiff materials, which do not fit closely elevations and depressions; on the face and on the fingers particularly, they tend to move, even after having been fastened with adhesive tape. There is need for a plastic material that does not have these disadvantages.

A lead-containing clay was compounded, as follows:

The mass is lead gray, nonsticky, slightly harder than soft putty, easily molded at room temperature, nonelastic and nonresilient. With the use of a round pencil as a
