Features • Uses Either an Internal or External Detector to Measure Alpha, Beta, or Gamma Radiation • Versatile — Can Operate as an Area Monitor or a Frisker • User-Adjustable Alarms • User-Programmable Units of Measurement, Either U.S. or SI Units • Power: Standard Alkaline (4) "AA" Batteries or 9 VDC Wall Mount Transformer Introduction The Model 3276 is a versatile instrument that can be used for multiple radiation detection or measurement purposes. It is used with either an internal or an external radiation detector to detect alpha, beta, or gamma radiation in applications such as frisking or area monitoring. It features a large, backlit, easy-to-read LCD screen and audible alarms and is controlled using a simple four-button interface. The unit body is made of lightweight, rugged aluminum. It is not intended for outdoor use and should be protected from splashing water. The attached metal handle facilitates transportation between sites. The instrument can be wall-mounted for area monitoring applications or mounted to a stand for desktop applications such as frisking (see options). The Model 3276 can measure radiation in count rate, exposure rate, exposure rate/dose, activity rate, integrated exposure/dose, time-averaged rates, and scaler counts. When used as a frisker, three modes of operation are available - RATE, MAX, and COUNT - which can be selected by pressing the MODE button. When used as an area monitor, only RATE mode is available by default. Measurements can be collected in two sets of units (primary and secondary) for RATE and MAX modes in cps, cpm, Bq, dpm, R/hr, or Sv/h units. The user can switch between the two sets of units by pressing the UNITS button. When used as a frisker with a scintillation detector, a sigma audio mode can be enabled that allows the user to find small increases above the background radiation level. Instrument setup can be done either through the front-panel controls or via the Lumic Calibration Kit (PN: 4519-865). Power is supplied by either four alkaline "AA" batteries or a 9 Vdc wall mount transformer. The Model 3276 is shipped ready to use with batteries, a wall transformer, and a calibration certificate. Area Monitor Configurations (internal detectors) * 3276/1 Note: While the detector used in this instrument is sensitive and is often used for detection of near-background levels of radiation, its nonlinear energy response means that dose and exposure measurements may be over/underreported.
