Model 3001-3RK Emergency Kit

3001-3RK emergency kit

Pancake G-M, NaI Scintillation and High Range G-M Probes

Alpha, Beta, Gamma


The Model 3001-3RK (formerly called Model 3001-3RK2) consists of several dependable, high-quality detectors matched with the versatile Model 3001 survey meter. The devices are packaged in a rugged transport and storage case with the required batteries, cable, and calibration certificate for a radiation emergency response kit.

The primary instrument, the Model 3001, is an ergonomically-designed instrument with four selectable detector buttons, enabling the user to quickly exchange detectors in the field. Alpha, beta, and gamma surveys may be conducted in two sets of units. The desired unit is chosen by pressing the Units button. A color-coded button selects the desired detector. An internal switch is used to enable or disable the front-panel setup feature to protect desired settings from inadvertent modification. Three modes of operation - RATE, MAX, and COUNT - are available. A large back-lit LCD screen, intuitive interface, warning alarm, and durable, splash-proof construction mean the Model 3001 will be the instrument of choice for your kit.

Three detectors, the popular Model 44-9 alpha-beta-gamma detector, Model 133-6 gamma detector, and the Model 44-2 high-energy gamma detector, accompany the Model 3001.

The transport and storage case includes dense pick-and-pluck foam, watertight capability, and hasps with padlock holes for additional security. A manual pressure relief valve is used in consideration of potential transport by aircraft.

Ludlum provides a 1 µCi ( 137 Cs) check source, check source holder, cable, and calibration certificate making this kit ready-to-go.

Ludlum offers several versions of pre-packaged response kits suitable for a wide variety of applications. If you desire more or different detectors, or other changes to our standard kits, please contact us regarding a customized kit.
