ABSTRACT:
A first radioactive source assembly disposed in a first source channel and a guide tube connected to the source channel and having a second end which is disposable in the animal body. A first source assembly transport thread connects the first source assembly to a first source assembly drive for driving the first source assembly to the second end of the guide tube. At least one further radioactive source assembly is disposed in a further source channel, a connector tube connects the further source channel and a connector disposed in the guide tube. A juncture is formed at the connector. A further source assembly transport thread is attached to the further source assembly and to a further source assembly drive for driving the further source assembly towards said second end of the said guide tube. The first source assembly and the further source assembly are alternatingly drivable toward the second end of the guide tube. A detector detects the presence of either source assembly in the juncture whereby radiation therapy may be accurately effected by either the first source assembly or the further source assembly.
