ON SALE NOW!! Do you know if you are being exposed to harmful radiation? The RDX-2 affordable hand-held portable radiation meter is small enough to go anywhere and as sensitive as the $1000 professional models since RDX-2 Detects minuscule amounts of gamma, beta or X-rays. The units Geiger Muller tube Detects all gamma and beta isotopes released by nuclear power plants such as iodine and cesium. It is ideal for Homeland Security and for detecting environmental / industrial contamination. It can be used to screen for radiation in air, food and water. Designed for nontechnical persons the RDX-2 uses a very sensitive 200VDC, Geiger Muller tube detector; and yet offers easy one-button operation.

Direct-Reading Dosimeter - W725, 0-5R with Sapphire Window Model W725 0-5R
Direct-Reading Dosimeter with Sapphire Window
Model W725 Order (4349)
The Direct-Reading Dosimeter is pocket-size, carbon-fiber electroscope with an ion chamber for detecting and indication of integrated exposure to Gamma and X-Ray radiation. It has a thin wall which permits the penetration and detection of radiation. This model comes with a hardened sapphire window that won't scratch even in the toughest of conditions.
Dosimeters are extremely sensitive instruments. Although they are constructed for rugged use, they should receive the same care as a wristwatch. Since dosimeters are hermetically sealed at the factory, they cannot be repaired or adjusted in the field. Therefore, if instrument malfunctioning is experienced, the instrument should be returned to the factory or your dealer. Dosimeters may be maintained in operating condition simply by cleaning the eyepiece lens and the charging switch insulator with clean water and a cloth that is free of lint and grit. Make sure the charging switch insulator is absolutely free of lint and moisture at all times. Caution: Do not insert any sharp objects into, or tamper with parts in the charging switch recess. Irreparable damage may be done.
Arrow-Tech, Inc. recommends a yearly calibration of the Direct-Reading Dosimeter which is generally consistent with good health physics practices. More frequent calibration may be necessary should the user's license require a shorter calibration interval.
