| 摘要 |
A device for storing a source of photons and for irradiating a body by the radiation from said source, comprising a body for biological protection provided with a cylindrical cavity of circular section and two so-called first and second passages respectively, these passages opening at one and the other of their ends in said cavity and on the outer wall of the body, a disc for biological protection, whose shape is complementary of that of the cavity of the body and presenting, on the one hand, a housing centered on an axis perpendicular to the axis of the cavity, this housing opening out on the side wall of the disc, a source of Y radiation contained in said housing, a precollimator disposed at right angles to said first passage, means for rotating said disc between a first position for which said source is opposite the precollimator and a second position for which the source is in stored position.
