## Overview

The International Medcom Radalert 100X is a professional-grade Geiger counter featuring a halogen-quenched Geiger-Mueller detector that accurately measures alpha, beta, gamma, and X-radiation. It offers a fast 3-second update rate, a versatile LCD display with multiple unit options, and a user-adjustable alert system. Built with durable stainless steel and a mica window, it ensures reliable field use. Powered by a single 9V battery, it delivers up to 2000 hours of operation, making it ideal for radiation leak detection, regulatory compliance, and scientific applications.

## Description

The Radalert 100X is a general purpose geiger counter that measures alpha, beta, gamma, and X-radiation. Features of the Radalert 100X, include a three-second update and a Utility Menu that allows you to change the default settings for several operating parameters. Its digital liquid crystal display (LCD) shows the current radiation level in your choice of SI units (microsieverts per hour) from 0.000 to 1,100 and counts per minute (CPM) from 0 to 350,000 or counts per second (CPS) from 0 to 3,500. For users of conventional units mR/hr (milliroentgens per hour) from 0.000 to 110 and CPM are optional in the Utility Menu. This instrument also offers an accumulated total and timer function up to 9,999,000 counts and 40 hours. Specifications Sensor: Halogen-quenched Geiger-Mueller detector (LND712) Mica end window density is 1.5-2.0 mg/cm² Side wall is 0.012" #446 stainless steel Detects Alpha, Beta, Gamma, and X-radiation Display: 4-digit liquid crystal display with mode indicators Accuracy: ±10% typical; ±15% max. (µSv/hr and mR/hr modes) Alert: User-adjustable alert level to 500 µSv/hr and 60,000 CPM. Beeper sounds the alert Anti-Saturation: Readout holds at full scale in fields up to 100 times the maximum reading. Temperature Range: -20º to +50º C , -4º to +122º F. Size: 150 x 80 x 30 mm (5.9″ x 3.2″ x 1.2″). Weight: 225 grams (8 oz) including battery.

## Questions & Answers

**Q: Is the product calibreted based on the old background radiation levels before Fukishima nuclear power plant incident in Japan?**
A: We have not adjusted our instrument calibrations to compensate for the Fukushima Daiichi event.   The activity displayed on our instruments reflects the actual radiation level.  So if you are in a low background radiation location it will reflect that, and if you are in a hot spot it will reflect that.   We do the background testing of each of our instruments in a low background radiation level environment and reference our calibrations to an independent lab with NIST source.

**Q: At what radiation level does this detector saturate?**
A: The instrument incorporates  anti-jam technology to prevent saturation from displaying false low radiation readings if the tube saturates (at very high radiation levels).  We periodically test random instruments in 20 R/hr radiation fields for quality assurance.   If you are working in radiation fields that high we recommend being very careful.

**Q: Hi. where is the product made? and also can i use this to detect leak for product inspection machine like x-ray? thanks**
A: Hello!  The Radalert100X is designed and manufactured in the USA at our headquarters in Sebastopol, California.  It's generally very good for detecting leaks and scatter from x-ray machines.  The efficiency is highest in the 30 to 70 keV range.  If the X-Ray energy is lower that that the detector will be less efficient.  If you need to check for leakage and scatter this can help you a lot.  If you need accurate dose rate information an ionization chamber will be best choice, but quite a bit more expensive.  Stay safe!

**Q: I live 50 miles from nuclear plant. Will this meter max out if they have leak?**
A: Based on my 40 plus years of experience working with communities affected by nuclear events, under most circumstances your Radalert100X will not max during a nuclear power plant leak at a 50 mile distance.   In the extraordinary situations that occurred at Fukushima Daiichi and Chernobyl reactors there is the possibility that being directly in the downwind plume during precipitation could max out a Radalert100X at a 50 mile distance.  Usually the dispersion and distance would create conditions that would not max out the instrument.  Since the instrument has jam protection, if you do hit higher levels the display shows Range Full when the full scale condition is reached and the Red LED stays illuminated to let you know to get moving.  Hope this helps.
