General Information The NeutronRAE II an intrinsically safe rapid detector of y ray gamma and neutron radiation sources Because of its high sensitivity it can alert first responders to the presence of a radiation threat well before they might be exposed to health threatening levels It is the only personal radiation detector with a loud audible alarm big bright flashing LEDs and a vibration alarm For stealth operations law enforcement personnel can disable each alarm separately NeutronRAE Is water resistant design makes for reliable operation in wet environments Its sensitive Cesium Iodide CsI and Lithium Iodide Lil scintillators provide fast less than 2 seconds for gamma 5 seconds for neutron response to radiological threats The NeutronRAE II accumulates approximate dosage Stored dosage data can be cumulative or cleared and reset for each use period Inserting amp Replacing Batteries NeutronRAE II uses two AA alkaline batteries as its power source use only Duracell MN1500 or Energizer E91 To change the batteries fo 1 Use a coin or screwdriver to open the cover on the side of the unit Turn the screw counterclockwise to loosen the screw and then tilt the cover off W E 2 Insert batteries into _ the compartment according to the legend on the rear of the NeutronRAE II making sure the batteries polarity is correct 3 Replace the cover and turn the screw clockwise to secure the cover
