• The portable Model 702i radiation surveillance and measurement system was developed to provide end users such as first responders a simple tool to quickly locate any abnormal levels of radioactivity and accurately identify the isotopes present. It additionally offers several advanced features for well-trained experts seeking to perform more detailed analysis either in the field or in a laboratory. Connection to a PC is available via a built-in Ethernet connection where stored or real-time collected data can be processed by optional isotopic analysis programs.
• Like other Ludlum Model 700 Series Identifiers, it employs time-slicing and patented Quadratic Compression Conversion (QCC) technology that delivers improved energy resolution, real-time background subtraction, and the highest degree of sensitivity. These units have a trace amount of 40K embedded to provide gain stabilization and selfcalibration. All captured spectra data are stored to a removable compact flash card in ANSI N42.42 standard format. This convenient storage medium facilitates quick removal for review elsewhere as well as allowing virtually an unlimited number of spectra to be collected while in the field.
• The design is also optimized for portability, userfriendliness, and rugged use out in the field. The ergonomic shape and overall balance allow them to be operated with a single (gloved) hand with easy thumb access to a set of large tactile type control buttons.
• The 8.9 cm (3.5 in.) color LCD is a transflective type, which actually brightens with use in bright sunlight conditions that typically render other types of LCDs useless. The use of color on the different displays is intelligently applied to depict the difference between gamma and neutron data, signifying the appropriate activity levels for capturing spectra, labeling isotope categories, and presenting alarms. Audible feedback and voice alerts further enhance the user interface.
• The instrument is powered with rechargeable NiMH batteries delivering up to eight hours of portable use and comes with an adaptor that accepts common alkaline batteries in the event backup power is warranted
