This is my somewhat "new member" explanation: Netc shows several types of detector stations, not only the private ones of its members. Each station has a number before the unique ID, ranging from 1 to 6.
1: are members' private detectors, primarily for both beta and gamma, of similar types as on radiationnetwork.com
2: does not seem to be used
3: does not seem to be used
4: are obtained from the EPA's Beta stations that use a more sensitive detector than most private users.
5: are obtained from the EPA's Gamma stations, but only one of the 8 energy bands they measure (the one suited for seeing man-made accidents).
6: are Japan network stations, and they appear to be also similar types to private detectors, but display in a different measurement unit.

If you only look at 1: readings, they should pretty much agree with radiationnetwork.com. 4: and 5: numbers are higher due to the more sensitive sensors. Note that paying members can see all of the above and can show selected types on an interactive map. I believe non-paying public users do not see 5: stations.

Incidentally, there are other sites as well with private type of detectors, such as http://www.radmon.org, http://www.blackcatsystems.com/RadMap/map.html, gcmap.com (there may be others). The first 2 seem as reliable as radiationnetwork. Gcmap.com has good detectors too (I own one), but on their map it's hard to weed out the non-current data.

Here is how I use radiation sites. I am a member of Netc.com and Radmon.org, with a detector connected to each system. Sometimes I want to see what is happening around the world and click some of my 8 bookmarked sites. Mostly I rely on email alerts sent to my phone. Netc is the only site that uses 'significant change' as an alarm no matter what detector is used (it tracks at least 3 types), and also sends alarms for detectors near to my location. Other sites use absolute value for the map display, and Radmon sends me email alerts from my personal site if it exceeds the value.

Alerts sent to me so far from Netc happen more frequently, and I appreciate the notification that something nearby is exceeding a 3 month window. A quick check with Radmon or one of the other level-based sites shows the local and world-wide situation based on icon colors. If these checks show no corroborating high levels, then there is no reason for me to take action. Yes, Netc sends alarms for normal seasonal rises, but that is far better than missing a release from a nearby reactor. Netc also send alarms for natural Radon washouts, as do others, but again I really want to know this when it happens so my family can avoid contact with the rain to minimize risk.

I am still trying to learn about radiation and natural vs. man-made releases, and I have to say that the radiationnetwork.com 'message' pages have provided the most believable analysis of private 'spikes' that I have seen so far.

When I first started I was a member of BlacKCat Systems but then graduated to Radiation Network and later graduated to NETC. Using NETC and their custom software on the Raspberry Pi, I do not need to leave a laptop computer running 24/7 anymore. I still own my BlackCat Systems GM-45 pancake geiger counter (which will work on NETC using the NETC Windows software) but I have no use for it anymore. I prefer the outside geiger counter (GMC-200) monitoring on an air purifier, although anyone familiar with my posts will already know that. If you want to learn more about my setup and my readings, please read this post:

https://www.netc.com/bb/viewtopic.php?f=13&t=203

For field testing I own an InspectorEXP and a Mazur 9000 pancake type geiger counter.

I am new here. I have my CHP part 1 and NRRPT and have worked in the nuclear field for years. I was noticing your ICONS for levels above average background on your map. I think that these are true but can be misleading. Rain events, a lot of rain 1/2 inch or more in a hour can cause significant spikes in background radiation levels. I have seen that around Oak Ridge TN with Gamma tracers. These ALWAYS related to increase in rain and had were not relatable back to a release. I appreciate your effort here but think that your reporting system could be misleading or not understood by a layman in this field. Has any thought been given to natural phenomena , mostly rain events and asking your station operators to discount these in their average? Thanks like I said I am new and just want clarification.

@normanmiller1 - Welcome to NETC. Your first post is a very interesting one considering you profess yourself as having so much radiation knowledge and yet you want our users & staff to discount every elevated rainfall reading to date. The original Fukushima plume did pass over the United States, that is a recorded fact. Elevated levels as a result of just that plume did happen with the help of rainfall that brought it to the ground. Why do you think the U.S. raised the allowable level of radiation contamination in our food & water? Do you really think it has been found safer for us to drink & eat? You really need to read through the news links here: https://www.netc.com/bb/viewforum.php?f=22

@normanmiller1 - Anyone with knowledge of the Chernobyl accident and how the world first found out about it through the elevated levels in the rainfall know the truth. You seem very sure of yourself using caps on the word "always" in your previous post. Even the FDA DOES NOT say Fukushima fallout IS NOT IN OUR FOOD SUPPLY, they admit it is because that's a fact. The FDA just reassures the public (like the Japanese government) that the radiation contamination is safe for us. You should be more careful with your wording and learn how to really read what is being said in these official government reports/releases. The Fukushima disaster is a never ending commercial dirty bomb and the media is pushing the global warming topic like a magicians slide of hand trick.

Quote:
March 2014 Update

To date, FDA has no evidence that radionuclides from the Fukushima incident are present in the U.S. food supply at levels that would pose a public health concern. This is true for both FDA-regulated food products imported from Japan and U.S. domestic food products, including seafood caught off the coast of the United States
