Radiochromic dye film for alpha/neutron dosimetry

["DR MW CHARLES" <charlemw@novell1.bham.ac.uk>]

Radiochromic dye film is a useful dosimetric material for dose 
mapping.  A radiation induced colour change can easily be quantified 
using microdensitometry to provide rapid 2 or 3 dimensional dose 
distributions.  We use this regularly for the dosimetry of 
microscopic radioactive particles (hot particles). Our work to date 
has involved hot-particles which are primarily beta /gamma emitters 
such as cobalt 60. We would like to extend this work to look at high 
LET radiations such as alpha radiation (also from hot - particles) 
and neutrons.  Does anyone have any experience or know of any 
references to the use of radiochromic dyes for high LET radiation 
dosimetry?
