ey, the positive Humidry samples. The quantity of radioactive gases collected in the B-31 device is unknown, qs radiac readings were obscured by surface contamination on the B-31 containers. The value of these samples can betcer be ascertained after preliminary laboratory analyses. All the above samples are now in ZI laboratories and under process, Project 7.4 - Propagation of Seismic Waves (J. -llen Crocker) Current reports from Washington, D.C., indicate that six stations and no report from one station. Another station reported "no signal"; it is believed that the tegative result from this station was due to faulty instrumentation, if tat yk eat received strong signals, one station fair, one station questionable, It has also been reported that some Coast and Geodetic Survey Beismic etations have retorted positive signals. Details of the mazcitude of these Signals and their respective / . locations are not currently available at this headquarters. Project’ 7.5 - Transportstion of Airborne Debris (P. W. Allen) Data were obtaineé to determine cloud height and movement after POWCPTIaE, ee NN RA ON he 6 EO EO. ate eee es Mize Shot. Because of the conflicting data reflecting the true height of the Mike cloud, conclusions will be held in abeyance until such time that critical evaluatic: of all data will yield the most probable height and path of the Mike cicud. Project 7.6 - Detection 2% Fireball Light at Distances (M. H. Olesca) No results of chit program are evaileble at this time. Copleaspo E LANL, J-Dly, Measurements 7-$ — /6
