Dear Stefano,
I was thinking to the Italian political and informative movement Alternativa, by Giulietto Chiesa. They can maybe be interested in spreading the idea a low-cost, efficient radioactivity detector, as nobody can trust the official estimates of Power, pushing for building new nuclear plants. See what's going on in Japan (possible melting of more than one nucleus, the worste nuclear accidente ever) while International infotainment is saying quite nothing. great ! you exactly describe what I ment.
It's not clear how your business is in line with public interests, e.g. how this production would cost less than a standard geiger counter. You can find counters for less than 200 euros. I dont know how the price will be now, but I think it only depends on the number of chips produced. I think the target price should be below 100 Euro. I try to find out the possible price after the presentation of the proposal.
regards, Leopold
