Nuclear Radiation Monitor & Alarm
Battery, Instruction Manual and Calibration Certificate
Use the RADALERT-100 to:
* Monitor personal radiation exposure
* Monitor an area or perimeter
* Detect radiation leaks and check for contamination
* Monitor low-level emissions from television sets and computer screens
* Monitor changes or critical increases in background radiation levels
* Find radioactive items in the workplace or home
* Check for radioactive deposits in the ground
* Check for X-ray scatter
* Locate spills and lost materials
* Evaluation of radioactive minerals and prospecting
* Safety-testing of home items, such as old-style radium-glow watches & clocks, uranium-glass and uranium-containing pottery glazes and ceramics.
* For emergency planning: nuclear power-plant accidents & terror incidents
The RadAlert-100 Geiger-Muller counter is a breakthrough in price and technology for personal radiation detection and protection. This small unit detects a full spectrum of ionizing radiations, to include x-ray, alpha, beta and gamma, and additionally incorporates an adjustable alarm feature, to automatically alert you to higher-than-normal radiation levels. During normal operation, the counts per minute appear on the digital display, with a flashing red LED and audio chirp (which can be shut off if desired), refreshing each minute. Or it can be set to gather the radiation dose over time if set into the totaling mode. The RadAlert can thereby be used for seeking out radiaiton "hot-spots" or evaluating materials which give immediate strong reactions, or alternatively allow one to make averaging determinations of low level radiation exposures over longer periods. The time-totaling feature is useful when evaluating low-level exposures from devices, materials or locations (as from TV's, CRT's, radiation-containing rocks, or Radon in a basement). One can then compare such timed readings to similar readings made in the open air, from background radiation alone. The RadAlert easily fits into a briefcase, purse, or large pocket, and has a belt clip for easy carrying and access. It operates from an included standard 9 volt battery for easy portable use.

The RADALERT-100 comes assembled and tested, ready to use.
Includes battery, carrying case, calibration certificate and operating manual.
The included Instruction Manual can also be obtained and examined in advance of your purchase directly from the manufacturer as a downloadable PDF.
Warranty: All our meters and devices are warranted by the manufacturer against defects of materials and workmanship, excluding abuse or misuse or breakage of parts by the purchaser, for a period of one year from the date of purchase. We will either repair or replace defective meters or devices with one of equal quality. For the RadAlert, while there is a one year warranty on the overall device, be aware that repeated exposures of the Geiger tube and/or LCD to very high levels of radiation may cause them to malfunction -- only a 3 months warranty is therefore offered on those two components. This will not be an issue except for those who plan to use the device in very high radiation environments, close to or exceeding the upper measuring limits of the device.

Also Available, an Optional Data-Acquisitions Software Package:
The GeigerGraph software works with the Radalert 100 (or the older Radalert 50 model), by receiving each pulse or count from the instrument to your Windows-PC computer using the included data cable. It then displays and graphs the Current reading, an Average, and Minimum and Maximum counts per minute (CPM) over the test period.
The GeigerGraph software is useful for continuous monitoring of environmental radiation. It alerts you to any elevated levels relative to your typical background count. The software gives an audible and visual alert whenever the CPM exceed a user-determined level. For example, in the picture above, the radiation level increases to above the user-set Alert Level of 100 CPM halfway through the test period, and the software issues a visual alert.
Features:
* Runs on any PC with Windows 95 or higher. Minimum system requirements: Pentium Processor (486 may work), CD-ROM drive (or 3.5" floppy disk drive), available serial port, 16MB RAM (more recommended), 1MB hard drive space, and high color (16 bit) display.
* Can run in the background, and notify you only if the radiation level exceeds your pre-set Alert Level.
* Saves the radiation count data every minute to a text file that can be exported to a spreadsheet program such as Excel or Lotus 123 for further analysis.
* Includes a simulation that mimics the recording and graphing of radiation counts without a Geiger counter. The simulation demonstrates the program, graphing normal background radiation followed by an elevated radiation count from a simulated radioactive "event" that exceeds the alert level.
* Includes a data cable with a 3.5 mm stereo plug that plugs into the geiger counter's dual miniature jack. The output at the tip of the plug provides a positive 5 volt pulse each time the Geiger counter detects a count. The other end of the data cable is a 9 pin RS-232 connector for an IBM PC compatible serial port.
* Comes on a CD-ROM which the user installs on the computer's hard drive, so the CD can be removed after installation for running of the program.
RADALERT "GeigerGraph" Computer Monitoring Program and Interface Cord
Price: $95.
Note: The RadAlert-100 will also function well with the Vernier data-acquisition system, using their digital interface and connect cables for radiation detection. The Vernier Logger Pro software is designed for both Mac and PC, and so is a good alternative to GeigerGraph, though a bit more expensive. See: Vernier Scientific
