An appliance for the interstitial radiation of organs in the body of man or animals comprises a cannular tube which contains a radioactive compound and which is attached to the end of a rod provided with a handle. A sheath can be adjustably displaced along the cannular tube and rod and is arranged to tightly surround the tube and rod. The sheath is radiation-absorbing at least at the outer part, which can be brought to cover, more or less, the radioactive compound in the cannular tube.
