Abstract
A radiation energy transmission system including source collimating apparatus and its method of construction for maintaining the intensity of a radiation signal emanating from a radiation source along a narrow signal beam path to provide for long distance transmission of the collimated signal sufficiently above background radiation level to be detected by detector means within the path of the beam and at the same time sufficiently below safe radiation exposure levels so as not to be harmful to personnel in the immediate area of the beam.
