Review: Great Product; Would Recommend! - I found this product to be solid and exactly as described. I am only a amateur scientist and wanted to measure various sources around the house/outdoor environment. This device was sensitive enough to detect particles being produced by my granite countertops, which exceeded my normal background radiation for my area by about double CPM. I purchased this product due to the price point, reviews and the fact it can detect alpha/beta/gamma radiation. Furthermore, I contacted the company directly several times to get various questions answered. I found they were professional, detailed and prompt with their replies. I would buy again if I needed another, but I think this one will suffice for some time. I noted it was factory calibrated with CS-137 and has a certification sticker on the back with date/technician name. For the professional it's noted in the description it can be NRC certified if needed for addition cost, but for my needs factory calibration is sufficient. I found this to be a great Geiger Counter and would highly recommend.
Review: It has been good - I have had this for several years and found it to be accurate and reliable. I also appreciate working with the company - if you need something you can email them and they'll get right back to you.

## 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.

### ⭐ Calibration/ material
*by N***. on October 16, 2024*

The instrument is calibrated once a year. Calibration was done 10 months prior to purchase. Also feels cheaply made. Clasps, wand and housing is made of plastic. Battery was not included, neither was a functional charger.
