1976 environmental monitoring report
The environmental levels of radioactivity and other environmental pollutants found in the vicinity of Brookhaven National Laboratory during 1976 are summarized. As an aid in the interpretation of the data, the amounts of radioactivity and other pollutants released in airborne and liquid effluents from Laboratory facilities to the environment are also indicated. The environmental data includes external radiation levels; radioactive air particulates; tritium and iodine concentrations; the amounts and concentrations of radioactivity in precipitation; the amounts and concentrations of radioactivity in and the quality of the stream into which liquid effluents are released; the concentrations of radioactivity in sediments and biota from the stream; the concentrations of radioactivity in and the quality of ground waters underlying the Laboratory; and concentrations of radioactivity in milk, grass, and soil samples obtained in the vicinity of the Laboratory. The external radiation level for 1976 at the north boundary of the Laboratory attributable to an ecology forest irradiation source was 74.4 mrem, or 14 percent of the applicable Radiation Protection Standard.

Acoustic and turbulent agglomeration of sodium aerosols. Quarterly report, January 1, 1977--March 31, 1977
Tests of turbulent and acoustic agglomeration of captive sodium fire aerosols at concentrations of 0.1 to 20 gm/m/sup 3/ were conducted in 90 m/sup 3/ and 0.65 m/sup 3/ vessels to evaluate these mechanisms for direct application air cleaning systems. Aerosol mass concentration decay with time was monitored by sequential filter samples. Turbulence was generated mechanically with a 51 cm diameter centrifugal fan impeller and a reverberant acoustic field was created with an electronic siren. The effectiveness of each method over a range of particle concentrations and power densities was evaluated by an agglomeration index, a measurement of particle growth based on sedimentation characteristics. Both turbulent and acoustic treatment markedly enhanced sedimentation rate compared to undisturbed settling. The effectiveness of both methods increased with increasing aerosol mass concentration and increasing power input per unit volume of aerosol. The agglomeration index reached 20 for turbulent agglomeration at an aerosol mass concentration of 3 gm/m/sup 3/ and 7 for acoustic agglomeration at 14 gm/m/sup 3/ when using an acoustic intensity of 145 dB. Turbulent agglomeration was more effective than acoustic agglomeration for the same mass concentration and power density conditions.

Additive enhancement of short pulse flashlamps
A key factor in the development of iodine photodisassociation lasers is the improvement of pump lamp efficiency in the 250 to 300 nm pump band at pulsewidths of about 10 ..mu..s. Previous work by Gusinow showed that certain metal additives appeared to enhance pump lamp output in the 250 to 300 nm region by as much as a factor of three. This had been determined by comparing microdensitometer traces of spectrograms of doped and undoped lamps. The principal problems noted with these lamps were a shot-to-shot variability of more than 30% and an effective life of only 20 shots (a result of migration of the dopants from between the electrodes to the colder regions behind the electrodes).
