Question 1

How do i get an nrc certification ? how much is it ? whom do i pay ? thank you.

Accepted Answer

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.

Question 2

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 ?

Accepted Answer

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.

Question 3

Does the manufacturer make a storage case for this unit?

Accepted Answer

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.

Question 4

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???

Accepted Answer

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.
