Abstract
The radioactivity of discrete areas of radioactive material on a surface region of a support layer is monitored by converting the radioactivity emitted by these areas into light emissions with the use of a suitable scintillant, and scanning the surface region with at least one photodetector in a plurality of discontinuous steps. Each step places the support layer and the or each photodetector in relative positions in which the or each photodetector detects at least a proportion of the light emissions activated by a respective one of the areas of radioactive material over a finite interval of time. A plurality of output signals are therefore produced by the photodetector(s), each of which is proportional to the radioactivity of a respective one of the areas of radioactive material.
