Subject: Re: Technical--Radition and Film Stock In-Reply-To: <[log in to unmask]> Message-ID: <Pine.SOL.3.91.951027085337.21985C@acacia> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII I'm not sure of the specifics for colour film, this will also depend on the stock that was used, but ionizing radiation will fog 35mm. Early methods of detection used film badges on nuclear personnel for this reason. Clumsily effective to measure the amount of exposure. One anecdote from the first blast at Trinity is that the Manhattan scientists were so worried about the fallout covering the state, some bright spark suggested tracing the line of complaints residents made to their local drug stores when they discovered their still and movie film was fogged. Actually turnd out to be a dud batch from the lab! Radiation also effects videotape. I've seen documentaries on Chernobyl with images taken on the reactor roof while firemen were battling the blaze. The video was streaked with flecks of light, oddly similar to night vision imagery. Let me know what else you turn up, as I'm still actively researching the nuclear film genre. Mick Broderick, UTS.
