Abstract
Radioactive sources are made from a foil (10) containing radioactive material, by cutting out hexagonal foil elements (12) from the foil, leaving no uncut portions of foil between adjacent hexagonal foil elements. This significantly induces wastage of radioactive foil.
Claims8
A method of making a multiplicity of radioactive sources (12) from a foil (10) containing radioactive material, characterised by cutting out a multiplicity of hexagonal foil elements (12) from the foil (10), leaving no uncut portions of foil (10) between adjacent hexagonal foil elements (12).
A method as claimed in any one of the preceding claims, further comprising locating the foil element (12) in a recess in a holder (40), and securing the foil in the recess by deforming the adjacent wall (44) of the holder.
A radioactive source made by a method as claimed in any one of the preceding claims.
A radioactive source comprising a hexagonal foil element (12) containing radioactive material.
