It has better spatial resolution than the pink/green stuff, but works essentially the same way: a spot on the film turns from clear to blue when exposed to X-rays. It won't get fogged by indoor light (although watch out for UV or sunlight) and there's no development needed. Gafchromic sells a whole bunch of films; I'm afraid I don't remember which one you should get. They're rated by radiation dose, but I don't remember how many Grays per second an X-ray generator will deposit in the film... - Matt -- Matthew Franklin , Ph.D. Senior Scientist, ImClone Systems 180 Varick Street, 6th floor New York, NY 10014 phone:(917)606-4116 fax:(212)645-2054 Confidentiality Note: This e-mail, and any attachment to it, contains privileged and confidential information intended only for the use of the individual(s) or entity named on the e-mail.
