Abstract 

Experimentation on an RT250 Phillips X-ray machine, used to treat superficial skin lesions, led to the discovery of deformed treatment fields, which was investigated using X-ray film. The cause of the field irregularity was found to be due to the circular applicators becoming misaligned in the housing. The treatment field was deformed when using the 3cm and 3.5cm applicators giving grounds to recommend the removal of these applicators from clinical use.
