Technical Examples

The invention relates to a method and apparatus for determining the intensity distribution of a radiation field. In the method, the ionization caused by the radiation field is detected by parallel ionization detector planes arranged in an ionization chamber, two of which planes are formed of series of wires determining the position of an ionization event in the X and Y directions, which detector planes provide the X and Y co-ordinates X1, Y1 of the ionization event. The ionization event is created by photonuclear reaction products arising from the radiation.
