DX-1 Radiation Meter from its on Vimeo

Do you know if you are being exposed to harmful radiation? The DX-1 affordable hand-held portable radiation meter is small enough to go anywhere and as sensitive as the $1000 professional models since DX-1 detects minuscule amounts of gamma, beta or X-rays. The unit’s Geiger Müller 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 DX-1 uses a very sensitive 200VDC, Geiger Müller tube detector; and yet offers easy one-button operation. Visual and audible warnings are made by clicks from an internal speaker and given by the compressed-scale, analog display. Powered by a 9-Volt battery (included) that lasts 50 hours at normal background levels. An audible alarm is triggered when radiation levels exceed 10mR/hr, increasing in frequency in proportion to the radiation level. An LED indicator alerts you that meter is on and of battery condition upon each use.

The DX-1 was developed after the Three Mile Island nuclear meltdown and was the most popular Radiation Detector that was sold after the Chernobyl Nuclear Meltdown for official and private citizen use. Over 20,000 DX-1 have been sold worldwide since 1982. Each meter includes an instruction manual that contains basic operating information and information on the various types of radiation. The DX-1 instruments will last many years. Each unit comes with a 5-year warranty on the electronics and a 1-year warranty on the GM tube! Any warranty work is covered directly through the manufacturer, Industrial Test Systems, Inc.

Here's a chart identifying radiation levels measured by the DX-1 meter.
