IntroductionThe The 14C-RK Emergency Kit packages all the basic radiation measurement tools you’re likely to need to handle a radiological emergency into a convenient carrying case to facilitate a quick response when required. The kit includes Ludlum’s robust and versatile Model 14C Ratemeter that includes an internal energy compensated GM tube to perform exposure rate measurements up to 2000 mR/hr.

Responders can either plug in the external alpha beta gamma GM pancake probe (Model 44-9) for contamination measurements or the (Model 44-2) high-sensitivity gamma scintillator for locating the source of the high readings. The carrying case supplied with the kit is air- and watertight with cutouts for each device including a 137Cs check source to verify proper operation of the equipment.

Features • Ready-to-Go Kit • Robust Analog Ratemeter with Multiple Probes • Measures: • Alpha, Beta, and Gamma Contamination • Energy Compensated Exposure Rate • Includes a High-Sensitivity Gamma Probe for Quickly Finding Sources Part Number: 48-2653
