Contact was mde with interested agencies of the Arny, Navy and Air Force as well as the Atanic Energy Camission to determine what work of related mture was being pursued by necessary agencies, As well as mking recansendations for the purchase of instrunents then conmercially availnble, the cammittce drew up tentative specifications for some instruments incorporating features not present in instruments then in production, A, These recommendations were as follows: The Victorcer-247 fon chamber meter has four scale readings, 2.5mr per hour full scale, 1X, 10 X, 100 X, and 1000 X, It was desired to obtain 10 instruments modified to havo five seale rances, 2.5 mr per hour full scale, 1X, 10 X, 100 X, 1000 X, and 10,000 X, The instrument cominy did not consider this practical in accordance with their current production design so a foursscale instrument reading 10 X, 100 X, 1000 X, and 10,000 X was agreed upon. -l.a \ =P
