3. Iwas informed that the New York office (?) already had auto recording ~ instruments in place which would serve the same ‘purpose inasmuch as the weather people had been briefed to notify Mr. Brecizin or one of his assistants whenever this particular inotrument recorded 100 mr/hr which wopld be nearly off scale. In accordance with Colonel House's suggestions regarding film badges, I sent 12 badges to Rongerik on 25 February, with instructions for their storage and use. Mr Kapral has assured me that my instructions were followed, in that 6 badges were exposed during and after the first shot, and the other 6 left in storage for the second shot in case resupply of the island were delayed for any reason. At about 2330, 1 March, Major Robinson, WREP, received an info copy of a message addressed to CJIF 7 from Rongerik to the effect that the auto monitoring instrument was reading "100 plus" and had gone off scale at 02502, and was still off scale, Inquiries made here and at Elmer failed to establish the exact nature of the auto monitoring instrument; thus it could not be established what exactly was meant by "100 plus". After conference between Colonel Houghton, Colonel Hammond, Colonel Watkins, Major Robinson and myself it was decided that we should take advantage of a scheduled MATS flight to Kwajalein and send a monitor - myself - on that flight to meet the regular weather isdand service flight departing Kwajalein on Tuesday (2 Mar) morning at 0830, Upon arrival over Rongerik at about 0945, I requested the pilot to fly the length of the island at about 500' altitude. reading of 4 T-1B instruments was 200 mr/hr. and at the same height gave the same reading, During this pass the average Another pass across the island We circled the entire Atoll at 500' altitude and instrument readings were the same over each islet.
