Introduction

 

The portable Ludlum Model 702 radiation isotopic measurement system was developed to give end users like first responders a simple tool to quickly locate any abnormal levels of radioactivity and accurately identify the isotopes present.

 

The instrument is coupled to a 2" x 2" NaI radiation detector whose signal is gain stabilized and automatically calibrates itself via an embedded 40K source. The Model 702 additionally offers several advanced features for well trained experts seeking to perform more detailed analysis either in the field or in a laboratory.

 

Spectrums can be captured to a removable Compact Flash disk or sent to a PC via an Ethernet connection. Quantum PC software to analyze the spectra more thoroughly is included along with a NiMH battery charger.

 

 

Neutron Detection Capability

 

Ludlum also offers the Model 702-1 which adds a 3He neutron detector.  The detector is 1 in. in diameter by x 6.2 in. long (2.5 cm by 15.7 cm), is filled to 2 atmospheres,  and has a sensitivity of 13 cps/nv.  It is fed into a separate channel of the 702 and displays cps; there is no identification involved.  The part number for the Model 702-1 is: 48-3666.
