## Overview

The GCA-06W is a handheld, professional-grade Geiger counter featuring an American-made LND712 GM tube that detects Alpha, Beta, X-ray, and Gamma radiation with ultra-fine 0.001 mR/hr resolution and a broad 1000 mR/hr range. Designed for ease of use, it offers a clear LCD readout, external wand probe for surface scanning, and optional ANSI and NRC certifications, making it ideal for industrial, educational, and safety-conscious professionals.

## Description

The GCA-06W is a handheld personal nuclear radiation detector. A proven track record for detecting nuclear radiation in school physics lab, industrial settings, transport containers, top soil, granite table tops, scrap metal, oil fields, objects and interior spaces. The external wand makes it easier to search materials and surfaces for radioactivity. The GCA-06W detects Alpha, Beta, X-ray and Gamma radiation above 3 MeV, 50 KeV, and 7 KeV respectively. Easy to read LCD is a 2 line by 16 characters that provides a current count and radiation level readout. Simple front panel instrument controls make the GCA-06W easy to use. Toggle switches control all the front panel options. User can select a time period, type of measurements (Imperial or Metric). Measurements (counts per second) are converted into radiation levels (mR/hr or mSv/hr). Time selection switch allows Counts Per Second (CPS) or Counts Per Minute (CPM) mode. Factory calibrated using an NIST traceable source to insure measurements. Our NRC certification is available at additional cost from the manufacturer. The NRC certification certifies your Geiger counter has passed ANSI-STD N323A calibration using a NIST traceable source from an independent US licensed laboratory conforming to United States Nuclear Regulatory Commission NRC regulations 10-CFR-34 and 10-CFR-35 standards (available at additional costs through the manufacturer). Options: Jack for Headphones or External Speaker. External Power Supply included. 3.5mm Data Port for WIN PC and microcontroller interface. The WIN PC program requires optional 3.5mm to USB data cable. Secondary indicators; audio (clicks) and visual (LED) included. 9V battery (mobile operation) not included.

## Questions & Answers

**Q: How do i get an nrc certification ? how much is it ? whom do i pay ? thank you.**
A: After you receive the GCA-06W Geiger counter, you contact the manufacturer, Images SI Inc., to ship the GCA-06W  to the manufacturer for an NRC certification. The cost for the NRC certification is $125.00 plus shipping. The  GCA-06W is sent to a independent U.S. government licensed  lab that will perform the NRC certification. The process takes about two weeks after receipt of the GCA-06W by the manufacturer.

**Q: Does " nrc  certification ready mean " that i still have to send the item to a us lab. and spend 120 $ extra ? or is it all set to use ?**
A: Yes, ready means it is ready to be NRC certified. You would need to spend an additional $125.00 to have this certification performed. The Digital Geiger counter is ready to use, with or without the NRC certification. The NRC certification proves the accuracy of the radiation readings.

**Q: Does the manufacturer make a storage case for this unit?**
A: Not that I know of, but, if you go to a military surplus store, you will find an appropriate case for this detector. I recommend a semi hard bag or pouch.

**Q: My understanding is that g/m tube units like this "saturate" at higher levels (nuclear war or accident) of radiation, and indicate very low. true???**
A: All GM tubes saturate at high radiation levels. This particular GM tube would saturate around 10,000 pulses per second. We have laboratory tests up to one Rad of radiation.  At this high level the Geiger counter is still responding properly. We do not have the facilities to test above one Rad radiation level to determine how this Geiger counter would respond. Sorry.  If you want something to detect 1-10 Rads of radiation I would recommend purchasing an old 1960's ionization chamber civil defense meter off of ebay.
