Irradiation apparatus

A method and device for inserting radioactive radiation sources into applicators and for withdrawing the radiation source and depositing them in at least one shielded loading and/or storage station. To remove a radiation source from the loading and/or storage station a traction wire with a coupling effective in the direction of traction is advanced via a fork and a switch into the loading and/or storage station, coupled with the radiation source and withdrawn as far as a stop where it is uncoupled and the traction wire is withdrawn through the fork. To introduce the radiation source into the applicator, on the other hand, a thrust wire having a coupling effective only in the direction of thrust is brought via the fork up to the radiation source and, carrying the radiation source with it, is advanced via the switch into the applicator and withdrawn again leaving the source in the applicator.

A magnetic coupling for translatorily movable bodies that is made in one position, is arranged so that it can be broken, without external control, in another position. For this purpose the first body has a coupling element of permanently magnetic or magnetizable material, the second body has at least one complementary coupling element of permanently magnetic or magnetizable material, and a third body has a coupling element of permanently magnetic or magnetizable material cooperating with the second body. Arranged between the complementary coupling element of the second body and the coupling element of the third body that is a spacer which can be moved as desired between the working positions.

Magnetic coupling

A radiation treatment apparatus comprising a radiation shielding container (a rest container) having a plurality of first openings. A plurality of radiator holders are connected to respective drive cables, the radiator holders being axially insertable and removable from the openings by means of the drive cables through flexible hoses connected to the container at the openings. A common single drive unit is connected to all of the drive cables for joint movement of all the drive cables and therewith for joint insertion and joint removal of the radiator holders into and from the openings via the drive cables. A second radiation shielding container (an intermediate container) has a plurality of second openings for selectively receiving respective of the radiator holders. Hose coupling elements provide detachable through-connections of the free ends of the flexible hoses selectively to a respective one of the second openings or a respective hollow probe for treatment. The drive simultaneously inserts the radiator holders selected for treatment into the respective hollow probes and for simultaneously inserting the radiator holders not selected for treatment into the respective second openings, whereby the radiator holders not required at the time for treatment are guided through the respective flexible hoses into the respective second openings in the second radiation shielding container while the radiation holders required at the time for treatment are guided into the respective hollow probes.
