RAE Systems Introduces DoseRAE, an International Personal Electronic Gamma Radiation Dosimeter


SAN JOSE, Calif. January 30, 2007 RAE Systems Inc. (AMEX: RAE), a leading global provider of rapidly deployable sensor networks that enable customers to identify safety and security threats in real time, today introduced the DoseRAE and DoseRAE-P. Both are Geiger-Mueller tube-based, electronic, gamma radiation dosimeters. Key international markets for these monitoring instruments are first responders, nuclear power plants, research facilities, hospitals, and industrial locations using or producing radioactive gauges, oil exploration and imaging technology.

Most people are exposed to no more than five milliSieverts per year from natural background gamma radiation sources. The DoseRAE is a rugged, cellphone-sized, direct-reading electronic personal dosimeter that provides an easy way to monitor personal radiation dosages and to ensure that workers do not exceed the annual U.S. federal or international exposure limits of fifty milliSieverts, said Thomas Negre, RAE Systems Global Product Director for Instrumentation Products. These electronic dosimeters are an important addition to our offerings in the international safety and security markets. The DoseRAE alerts users to excessive exposure to radiation in a variety of working conditions.

Both DoseRAE models are rugged, lightweight, direct-reading electronic personal dosimeter that provides superior dose monitoring accuracy and can measure radiation exposure in Sieverts (SI Unit for radiation dose). The sensitivity of the Geiger-Mueller tube in both DoseRAE units provides accurate dose readings with a resolution of less than 0.02 microSieverts.

The DoseRAE’s settings can only be changed using the dosimeter reader, preventing wearers from inadvertently changing alarm set-points.
The DoseRAE-P (programmable) allows alarm settings to be changed “on-the-fly” using the dosimeter’s buttons.
Both units alert the user with a loud 75+dB alarm and big, bright, flashing, LEDs.

Both the DoseRAE and DoseRAE-P track stay-time, the amount of time left until the dose alarm level is reached if the wearer stays in an active radiation field. The units provide two levels of alarm:

a stay-time warning alarm
an absolute stay-time alarm
This gives the wearer plenty of advance notice to finish work in a radiation area before reaching the dose alarm threshold.

The product was jointly developed with Science Applications International Corporation (SAIC) (NYSE: SAI) and will be marketed internationally by RAE Systems and in the United States under the SAIC brand as the PD-3i and PD-10i. Under a separate license agreement, RAE Systems will manufacture product for both companies. Both the international and US versions of the dosimeter are available immediately.
