X-ray Surveys.
Two X-ray surveys have been carried out in the past 2 years, Surveys are done on 35 millimetre film and all radiological abnormalities are investigated by the Government Tuberculosis Service.
The first survey was carried out at Stanley Prison which waLS over-crowded, The prisoners, all males, were examined and all infectious cases of pulmonary tuberculosis isolated.
It was intended to deal similarly with all subsequent prisoners before admission but this proved impracticable.
The results of the survey were as follows :-
Number of inmates X-rayed
Number re-X-rayed (Large film)
Number of active cases
Percentage suffering from active tuberculosis
Long Term
