[Wood's alloy, a material suitable for quick production of individualized shielding blocks in the mantle technique (author's transl)].

The extended radiation therapy of lymphogranulomatosis by means of the mantle technique requires individualized focussed satelittes. The production of such individualized, ray divergences considering "lead mantles", however, needs some technical expenditure and causes loss of time. Using Wood's alloy, which has a shielding capacity similar to lead but is well and easily workable because of its low melting point, it is possible to obtain individually adjusted shielding blocks by casting.
