Are you living in radiation? How reliable are these websites?

[MakingMoneyHoney]

Nuclear Emergency Tracking Center clearly shows a lot of very high levels of radiation. Just how accurate is it? (When you click on the circles you can see the supposed levels of Counts per minute CPM)

Q: Can you better explain how these alerts start, and why they are canceled?

A: Netc.com tracks the radiation levels at over 3000 stations around the world. Some of the stations, collect gamma radiation and others collect dose rates. Each station has its own NORM (Natural Occurring Radiation Material) background level that is calculated everyday for three months. When the current radiation exceeds that level and other conditions are met, an Alert in issue: Saying the radiation at that station has increased radiation level that are higher the the 3 month range. This is very important, not because it is dangerous, but because high levels of radiation blows in the wind or rain and could be a health problem if it is breathe into your lungs. Just like a sand storm the radiation blows following the wind patterns, so then the Alert is cancelled when the radiation is within its radiation level.

There are other news stories about these things too:

Radio talk about radiation - They specifically mention Fukishima and San Francisco.

US radiation levels exceed evacuation level

""SAN FRANCISCO—High radiation levels exceeded the evacuation level requiring the wholesale evacuation of civilians at many locations in the States over the past four years, from 2011 to 2014. Those who remain are supposed to be wearing hazmat suits.

Did evacuation happen in your town or city? No, of course not. It did not happen anywhere that I know of.

This heavy radiation influx precedes the Fukushima Daiichi, Japan three reactor meltdowns. Therefore, by definition it cannot be just strictly from the Fukushima radiation releases. The killing radiation came from someplace else, plus Fukushima’s rad. This pattern is repeated again and again in cities throughout America. What happened to beautiful zapped America?

Certain scuttlebutt in the nuclear community is that America’s is the most irradiated population in the world. Getting zapped like that leads to “shortened life spans” in the quaint expression of the American Nuclear Regulatory Commission. It means the rad kills you before your time. This is from greatly increased rates of radiation induced heart disease, radiation induced cancers and hundreds of other radiation induced illnesses.

Today’s HazMat suit required and evacuation level cities include a lot of locations. Notable due to very high radiation levels are the following:

Billings, Montana, 769 CPM
Idaho Falls, Idaho, 488 CPM
Rapid City, South Dakota, 463 CPM
Grand Junction, Colorado, 465 CPM
Colorado Springs, Colorado, 536 CPM
San Diego, California, 417 CPM and
Raleigh, North Carolina, 474 CPM

The “evacuation required” level is 300 CPM (counts per minute). A single count is one radioactive decay."





This website still shows a bunch of radiation in the US, but the levels seem less... less as in you shouldn't evacuate, but still it's a lot of radiation we're living in, in the US, if this one is more accurate.

Edit: And if these sites are not accurate, where can we see some accurate stats?

Is that supposed to scare somebody?

OK then my attempt is better.

I knew Brazilian babes were hot but had no idea they were that hot.

[TECSHARE]

I am the owner of a Geiger counter, and I can confirm the readings of around 30cpm for the Chicagoland area. In fact where I live it is about half that.

[Balthazar]

Unfortunately, CPM alone says nothing. It depends on the device sensitivity, some detectors just like my NaI scintillator are saying 200-300 CPM while geiger counter would count only 7-8 decays per minute.

And even more funny, sensitivity is different for every tube even for same models with identical power supply. Just for example, one of my SBM-20 tubes has ~5% greater counting speed than the others.

Wow, that beach.

When did we get to the point everyone was ok to having this much radiation on this planet?

Well that's disturbing.

[Snail2]

Balthazar is right, CPM value on its own can be misleading, especially because a GM counter counts all sorts of radiation including alpha, beta and gamma rays. As an average wall or the body of a car can stop alpha and beta radiation, only the gamma radiation is a real issue, but that part could be much lower than the measured value.

[Schleicher]

This map is probably more useful than the geiger counter map:



Additional to that you have radiation from building materials (like granite or concrete)

Thanks. Of course according to that map, California, Arizona and Nevada seem to have a lot of 8.5, but does that mean?

Even if these are just small amounts of radiation, I still think it's weird people are ok with having these nuclear plants.

[Balthazar]

As an average wall or the body of a car can stop alpha and beta radiation, only the gamma radiation is a real issue, but that part could be much lower than the measured value.

Unfortunately, it's not quite correct because isotopes can be consumed with water or food.

Unlike gamma, alpha particles are able to give all of its energy to cells. That's why alpha radiation from Am241, Pu238-242 and some other isotopes is the real threat as well as reason of evacuation from the Chernobyl and Fukushima exclusion zones. On the other hand, people are able to live in gamma contaminated areas without noticeable problems. Just for example, 25% of Belarusian territory is contaminated with Cesium-137. Due to weak interaction with matter, gamma radiation is not a real issue unless there are really high levels of activity.

////

It should be noted that most of the dosimeters can see only gamma and hard beta radiation, this makes them useless for the assessment of a real threat.

If you need an explanation then there is an example:

Americium-241 emits alpha particles and weak gamma rays;
Cesium-137 emits hard gamma and beta rays;

If you would use typical geiger counter to compare Am241 and Cs137 sources with identical activity, then you will see lower CPM values for Am241 source. This will inevitably lead you to wrong conclusion.

Just re-posting this from another thread, if anyone is interested.

Fukushima/3 of the 4 Cores Now in Contact with Ground Water

July 20th, 2015 - Nuclear Expert: We should be very worried about ongoing catastrophe at Fukushima… “Complete failure” of ice wall built to contain extremely radioactive water… Plutonium is flowing into Pacific, will for many years to come — Strontium in ocean hits record level, huge increase reported since April

"Excerpts from presentation by Arnie Gundersen, Fairewinds Chief Engineer, Jul 16, 2015 (emphasis added):

    Are the meltdowns at Fukushima Daiichi over?… This catastrophe is not over… We should continue to be very worried.
    3 of the nuclear cores at Fukushima Daiichi are in direct contact with groundwater.  Nuclear power designers and engineers never anticipated that possibility.
    Fukushima Daiichi Units No. 1, No. 2, and No. 3 were destroyed… allowing holes and cracks to form… We know for sure that the Fukushima Daiichi containments are full of holes that allow groundwater to come in direct contact with each nuclear core.
    Groundwater is still leaking in and leaking out, at a rate of at least 300 tons per day… more than 1,500 days have passed… 23,000-tanker truckloads of radioactive water have already leaked into the Pacific Ocean. Worse yet, there is no end in sight.
    As Fairewinds anticipated, the ‘ice wall’ is a complete failure.
    Cesium, strontium and plutonium from Fukushima Daiichi will continue to bleed into the Pacific Ocean for decades because the groundwater flow is unmitigated.
    Japan’s press looks on silently due to the real threat and constraints of the government’s secrecy act… The true human, financial, and environmental costs of this nuclear power catastrophe are not publicized and discussed."

From 2013 - 3 Fukushima reactor cores melted into earth during accident, still missing – 4th could explode

Call me paranoid, but I never was a big fan of nuclear power stations. Hearing about the high radiation levels around just further solidifies my distaste for nuclear energy.

Why is that? If you do some research on the Pacific you will see it is largely a dead zone now with thousands of sea creatures washing up on beaches and almost no visible life in many areas. The levels are certainly elevated on the West coast of the US.

[BADecker]

All that radiation is simply American intelligence and ingenuity going nuclear.    

EDIT: Did I spell that right? Maybe it's "unclear."

At least you didn't spell it nucular like most people pronounce it after that idiot George bush started saying it that way.

[Balthazar]

Why is that?

Because it's a pure BS. There is no actual difference between chanting "allahu akbar" or pushing some anti-nuclear propaganda. Both are nothing but a result of ignorance.

If you do some research on the Pacific you will see it is largely a dead zone now with thousands of sea creatures washing up on beaches and almost no visible life in many areas.

If you do some research then you will see that these "elevated levels" are nothing but a joke in comparison with a natural radiation background in many populated areas of the world. And even more funny, natural radiation is provided mostly by the alpha emitters, which are dozens of times more hazardous for your health than all these anthropohenic beta- and gamma-emitters.

with thousands of sea creatures washing up on beaches

Isn't connected with radiation levels. You're welcome to prove otherwise.

Nuclear energy is the cheapest and the most environmentally friendly form of energy available. That is why the pro-OPEC types try to manipulate the general population in to thinking against the nuclear reactors. A massive negative propaganda campaign is ongoing against nuclear power, funded by the OPEC heavyweights such as Saudi Arabia and the United Arab Emirates.

[Balthazar]

Nuclear energy is the cheapest and the most environmentally friendly form of energy available.

Don't forget that it's nearly unlimited. If we switch our energy system to fast-neutron nuclear reactors, then we won't need oil, gas, coal and even uranium or thorium mines. These reactors are capable to burn virtually any actinide, including the weapons-grade plutonium. So, the current stock of long-living radioactive waste, such as americium, depleted uranium and plutonium, is more than sufficient to serve the dozens of generations as an energy source. No wonder these saudi monkeys are desperately trying to prevent this from happening.

[alyssa85]

There is natural radiation in rocks remember, particularly around mining sites. It's pretty much impossible to live on planet earth and have no radiation at all.
