A non-scintillating plastic sample in the form of a 6-mu m-thin film w
as exposed to a 1-MeV proton beam at dosages ranging from 10(7) to 10(
9) rad/cm(2). The film was found to be luminescent when exposed to ult
raviolet light. The intensity of the luminescence is a direct function
of the damage to the film and there is no evidence of luminescence on
unexposed regions. The luminescence increased to a maximum within 72
h after exposure and remained constant thereafter.
