Geiger Counter

Monitor 4

   This will help you find the small chunk of Chernobyl that you might have in your backyard. The Monitor 4 is a compact general purpose meter that will detect alpha, beta, gamma and x-rays. With the presence of radioactive material or radiation, a red light flashes, an audible beep sounds and the meter level will increase with rising levels. This unit can detect alpha radiation down to 2.5 MeV. Plastic carry case included. Requires (1) 9V battery, included. USA. Size 2.75" W x 5.75" H x 1.5" D.

"Total individual protection requires an integrated approach.  The primary protective mechanism is respiratory protection for both chemical and biological agents and especially so for biological agents.  A properly fitted protective mask when combined with an overgarment, gloves and boots can provide excellent protection." - Jane's Chem Bio Handbook
