Irradiance measurements of some UV sources

The use of UV radiation sources in the scientific, medical and industrial fields is becoming increasingly widespread. This poses the problem of protection and calls for a set of rules fixing the maximum exposure values for the organs subjected to the radiation hazard. The purpose of this work is to analyze some commonly used sources by first determining the spectral composition of the radiation emitted in the 200-400 nm range, and the total effective irradiance from which the maximum exposure time is inferred. The latter is measured on the basis of the criteria fixed by ACGIH. The final interests is that of providing some evaluation of the hazards connected with the use of some widely used sources.
