Aa me te th Operations: Seventeen stations operated to obtain information on the radiofrequency signal generated by each shot. All stations were dis- tant from the PPG except for one operated remotely by NBS on Eneu. Following contamination by BRAVO, this station was removed and relocated on Runit. Shots: All. Radiation Exposure Potential: For the remotely located stations, the potential was slight. A greater potential existed, however, for per- sonnel moving the contaminated NBS trailer from the initial location on Eneu to Runit after BRAVO. Staffing: One uniformed person was associated with this project, re- ceiving 0.915 R. Project Report: Reference 75. Project 7.2 -= Detection of Airborne Low-Frequency Sound from Nuclear Explosions Agencies: National Bureau of Standards (NBS) Naval Electronics Laboratory (NEL) Signal Corps Engineering Laboratories Office of Naval Research (ONR) Operations: Fifteen acoustic stations were operated to measure low- frequency sound. Shots: (SCEL) All stations were remote from the PPG. | All. Radiation Exposure Potential: Staffing: None, offsite operations. Not applicable, since all stations were remote from the PPG.
