GA-MA & ASSOCIATES, INC. products

The Marinelli type beakers of polypropylene are used for analyzing radioactive liquid or solid samples. GA-MA Beakers provide a convenient and cost-effective means for analyzing moderate to low activity level radioactive liquid or solid samples directly for gamma ray emitting isotopes. Use of disposable GA-MA Beakers eliminates the tedious and time-consuming process of evaporating large volumes of liquid samples in planchets prior to analysis.

GA-MA manufactures Marinelli type gas containers designated as GAS GA-MA Beakers. The containers are available for Germanium detectors as well as the Nal detectors. Gas containers are designed to be used with two valves, which permit the flushing, venting and containment of the radioactive gas samples. Gas containers are designed for disposable use and may be obtained for very economical prices when purchased in bulk quantities. Disposable use is appropriate for laboratories having large sample loads and/or low detection sensitivity requirements. The use of Gas beakers enables one to significantly reduce sample count times without sacrificing detection sensitivity. Thin walls minimize attenuation of low energy gamma ray lines, such as the 81 Kev gamma ray of Xe-133, normally found in nuclear power plant radwaste discharges and process streams.
