Does the radon level stay the same or it could be various? My radon level was 1 for half yearbut it goes to 1.8 recently. Because of the bad raining?

Seems to vary based upon how much the furnace/ac runs... if it runs more, reading drops to about 1.7; if it hasn't kicked on in a month, then peaks at about 2.8.

Yes, your radon levels can vary. My daughters readings have averaged from about 5 to about 8. You want to be at 4 or below. Hers seem to be affected by the level of activity in the home as well as the season. She lives in southern Minnesota, which is a heaven for radon. Her brother lives less than a mile from her and his radon levels are below 2. If you are under 2, count your blessings because you will not have to mitigate. We will be installing a radon mitigation system in her home this summer. Hope this helped.....Dennis Owens

Yes. Radon levels are usually just averages over periods of time because multiple environmental factors affect the period of time measured.

Your radon went up for a short period. Mine changes a little bit every day (1-day average), up or down, between 0.8 and 2.0. Radon levels (1 day and 7 day averages) are expected to fluctuate. Your annual average would change very slowly over the same periods of shorter term fluctuation.

Colorado has lots of natural radiation in the ground. So check with your county as to what are normal levels for that area. 25 does seem high.

Not a chance. When radon, a gas, is dissolved in water its molecules are too small for any filter. Radon's decay products, on the other hand, are "sticky" and might be caught up by a 1 micron or carbon filter. I copied the following information for you: In drinking water The effects of radon if ingested are similarly unknown, although studies have found that its biological half-life ranges from 30-70 minutes, with 90 percent removal at 100 minutes. In 1999 National Research Council investigated the issue of radon in drinking water. The risks associated with ingestion was considered almost negligible.[122] Water from underground sources may contain significant amounts of radon depending on the surrounding rock and soil conditions, whereas surface sources generally do not.[123] As well as being ingested through drinking water, radon is also released from water when temperature is increased, pressure is decreased and when water is aerated. Optimum conditions for radon release and exposure occur during showering. Water with a radon concentration of 104 pCi/L can increase the indoor airborne radon concentration by 1 pCi/L under normal conditions of water use.[124] filter. Two things are obvious from the above information. Boiling water outdoors would remove the radon gas and showering indoors is going to provide your most dangerous exposure. Being able to rapidly exhaust air during showers should be your highest priority. A good exhaust fan over the cooking area where water is boiled is probably second.

I have mine buried about 6 inches below ground, and it was negative temps here for a couple days this week. It worked fine.

We have this test meter for our community well. We fluorinate according to the EPA guidelines. It works well when it is calibrated. You have to have the 1% fluoride solution and the tabs to calibrate the meter. We had the meter for about 4 months and the sensor went bad. The company replaced it immediately at no cost but with the wrong part. It took several weeks to replace it with the right part. It was on B/O for some time. Now that we use it daily I can get an idea of the level we need to be at. It's a field test and they are not 100% but close enough for what we need. When our levels were low the meter just gave a Lo code. It am not confident it would give you a zero reading you may be looking for.

Mine are exposed and doing fine but only up for 1 year now. They face North so less sun exposure but more wind and weather exposure.

Stan, Sorry I don't have the quantitative data available such that I refer you to the manufacturer for it. Qualitatively, however, mine is doing a good job. Uncharacteristically we had a week of clouds and rain lately. As a result, the brightness and duration was impaired somewhat but at 0530 hours of the morning of the fifth day there was still a glow emitting from the 20-or-so LEDs. Now that we're past the autumnal equinox I expect some diminishment but we're more than likely to have clear than obscured skies at my altitude (~6700 ft) and latitude (~ 41degrees N) during the upcoming winter period.

Radon is a gas that is in quantities too small to be measured except by a long term test. Usually about four or five days. I have never heard of radon in the water but if so I am sure it is bleeding off into the air as gas as you run the water. You need to do a test of your home with a kit that is sent off to a lab.

well I also have 20 eggs in mine right now and we have almost the same readings and I have found that most temp gauges will read a little diff every time. Just don't let it get below 98.5 at tray and you should be ok as I have hatched twice now and it worked for me. Good luck and I hope this helped

Dan did a great job of answering your question. Keep an eye othe temp.....there are times I still need to add snow to keep it around 80

Aloha, I personally have changed temperature and have not encountered any problems. I enjoy using this unit. Hope this helps. Much Blessings

Have you reloads changed any would be the most obvious questions. I try to chronograph on cloudy days or in the shade beside a side of a building. Something that is solid shade. I just don't trust sunny days. Unlike others I don't trust sunny days.

My oven goes up to 550 degrees..it won't go higher than that..but I haven't had any problems so far putting the stones into it preheated. My stones are usually room temperature when I put them in. I've been using them for several months that way.

Hi Dan, you cannot detect "Radium" in water using this Detector, which is designed to detect Alpha and Beta Particles. So a paper towel wipe of your source water, placed in an isolating plastic bag, and measured with this detector should allow for a reasonable approximation of the radioactivity of the sample. The only reliable way to screen your water for Radon contamination is through titration QA analysis. Almost all ground water has measurable or detectable levels of Radon gas intrusion. Good luck and eat healthy and safe.

Mine was able to reach about 220 F using an accurate oven thermometer, but I did need to rotate the unit periodically to capture the most sunlight. The test day was clear,in the mid 70s and I'm sitting at about 38 degrees N latitude. That was actually the second day I tried. The first test out was disappointing since the temp only reached about 185 F. I have no idea why the difference but assume it was due to a few factors such as time of day and me rotating the unit more often during the second test. I haven't yet tried to cook anything.

Yes, I posted this question as well and accidentally deleted it I think as I don't see it anymore and five others had said yes, about the same said no. It did for me, I've been running it outside for a few days and it's getting less and less. I'm hopeful to bring it inside again tomorrow. It was rough the first day as my whole house smelled like chemicals.

Per Corentium customer support (support@corentium.com), I was told "for our digital radon monitor there is no need for a recalibration within the lifetime of the instrument." I am not affiliated with this company and do not own this unit, but I had emailed them previously out of my own curiosity.
