Thank you this is a great item and it came promptly on time and I love the product. I’m able to learn a little more about my environment. Thank you so much, Elizabeth.

So, she's a bit skittish.If it catches a few too many particles, too quickly, she goes up quick.No way to spread out the average, that I have found so far.That is NOT a problem, so long as you know wtf you are doing.TL;DR;Buy one. or 3. depending on your needs....I'm ordering another RIGHT NOW, same day I got the first.I have 2 Radex ONEs, which you might not be able to get anymore, and if you CAN, be suspect of them, as they are russian made.They are probably??? still ok?But I do NOT update them currently....Turned off auto update on the phone app also.I also have 2 RadiaCode 101's. but have not compared yet.Those are in deep protect. Wrapped up in Al Foil, no updates to the android app.A phone also wrapped...Same russia thing I think?I also have an olderhttps://www.amazon.com/gp/product/B00EZBOVKA/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1which is unavail, but mine still works great.With that history, this device has an AVERAGE flaw, in that it will FREAK YOU OUT for a short term source.However, mine did recover pretty quick from a uranium ore exposure, so I am gonna recommend this as a short term warning device, with long term monitoring abilities also.If it starts screaming, vibrating, do what the shepherd said. ( Really? Get the FLOCK out of there!!! )Once it slows down, maybe keep moving away, but don't kill yourself in a hurry.I LIKE it.It DOES work well,and it is CHEAP, for what it does.Does it do anything special?absolutely not.Look at the Radex One, yeah, from Russia, if you can even find one now.Also the Radiascan RadiaCode 101, however, I just looked these up, and they are CRAAZY right now.I got mine for $300, some guy has em for $700!!!!!!!!!!!!!!That is crazy!Look for other things close to as good.Yeah, buy two of these. Maybe 2 others with good reviews also.Wrap one up in Al foil.....

This is a high quality geiger counter considering the price. It can detect gamma, beta and x-radiation. Two screens are provided: the first is numerical and the second is graphical. Multiple units of measure are selectable from the setup screen. The manufacturing quality of this instrument is evident at first glance. It is beautifully packaged in order to protect the Geiger-Mueller tube in shipping which is otherwise subject to shock breakage. I purchased this item in order to monitor radioactivity in two places in my home. The first is an activated charcoal filter that I have on my water supply in the basement while the second is a reverse osmosis system with charcoal filters under the kitchen sink. Since there is radon in my well water supply, I prefer to remove as much as possible before it is delivered to the faucets in the house. It also serves to reduce the radon levels in air due to cooking, washing, showering and laundry. Capturing the radon in activated charcoal will also capture radon decay products (daughter products). Some of these have very short lifetimes, but some are extremely long and tend to build up in the activated charcoal filters over time. I wanted to see how these radiation levels increased over time in order to determine the optimal time to change the filters. The first thing that I noticed was that in just one week, after a basement filter change, the radiation had already built up by a significant amount. The radon in our water is approximately 3000 pCi/L. If allowed to vaporize due to cooking, washing, bathing and laundering, this amount of radiation could add about 0.3 pCi/cubic meter to the air. The radiation level that was measured close to the tank was 1.4 uSv/hr according to the meter. If multiplied by the number of hours in a year, 8760, we arrive at the accumulated dose per year which is 12.3 mSv. This is the amount of radiation exposure that would be possible were a person to stay in proximity to the tank for an entire year. This exceeds the NRC guidelines of 1 mSv per year. Clearly, the filter should not be placed anywhere near where people or children would normally gather or play, for example, a finished basement. I will be monitoring the activated charcoal filter tank for several weeks to see if the radiation buildup reaches equilibrium as the filter capacity is exhausted. This will provide a guideline for how often the filter should be replaced. Short term exposure to the filter during a filter change should not be an issue provided that safe handling practices are followed.
