The Japanese government says 20 workers at the disabled Fukushima Dai-ichi power plant have been decontaminated after exposure to radioactive material.

Dozens more, at least, have reportedly been decontaminated within the 12-mile evacuation zone around the plant after Geiger counters picked up evidence of radiation exposure.

That made us wonder just how someone gets decontaminated from radiation – which, after all, is invisible, odorless, tasteless and generally insidious. Most people think of it as “rays,” which is partially correct.

The answer might surprise you.

“Decontamination is very simple,” says Dr. Eric Toner of the University of Pittsburgh’s Center for Biosecurity, who has studied what might happen in the wake of a terrorist’s “dirty bomb” attack.

“As a rule of thumb, 80 percent of decontamination is removing your clothes,” says Toner, an emergency physician. “And 95 percent is removing your clothes and taking a shower — if possible, shampooing your hair. That’s all that’s involved. No fancy chemicals.”

That’s because radiation is carried on dust particles. “The air isn’t radioactive, but small dust particles are,” Toner explains. “You’re essentially washing off the dust.”

So a rain is a good thing at the time of, or after, a radiation leak. Rain washes the dust from the air, diluting it in runoff. (Yes, the runoff would be radioactive, but diluted — and presumably, the ground would also be getting radiation exposure already.)

Dry air, when dust gets kicked up in the air and disbursed over longer distances, is bad.

By the way, the dusty clothes can often be decontaminated simply by washing them, but it depends on the amount of radiation detected. “If you have reason to think they’re heavily contaminated, they should be disposed of properly,” Toner says. That means put in a plastic bag and, if possible, taking them to authorities for disposal.

All this raises another question – how to decide if somebody needs to be decontaminated.

At a place like the Fukushima power plant, where workers wear dosimeters that constantly record exposure and the environment is being continually monitored for radioactivity levels, the decision is clear-cut.

But it’s far less so out among the general public. In a situation like the current one, there’s a profound lack of information on radiation levels at different distances from the power plant and how they might be fluctuating over time.

In an emergency room or post-disaster setting, Toner says doctors would usually use a Geiger counter to screen people – before decontamination, to see if they’ve had any detectable exposure to start with, and afterward, to see if they still have traces of radioactive dust.

There is a lot of Geiger-countering going on in northern Japan right now – as most TV-watchers know by now. But using Geiger counter readings, given in “counts-per-minute,” or cpm, is not necessarily a great way to know if you need decontamination. Or whether it’s time to start taking potassium iodide pills to protect against thyroid cancer.

Steve Herman knows about that. He’s a correspondent for Voice of America who got a Geiger counter scan Thursday in Koriyama, a town 37 miles from the Fukushima Dai-ichi plant as the crow flies.

“My body 1,500 cpm, my boots 3,000 cpm. Another reporter: 10,000 cpm on her shoes,” Herman tweeted.

What to make of those readings? It’s hard to know.

“It is really hard to interpret Geiger counter cpm’s,” Toner says. “They vary from machine to machine. For example, they depend on the size of the probe – the bigger the probe, the more counts detected. And each machine must be calibrated against a known source (of radiation). Translating the cpm’s to an actual exposure does take a health physicist.”

In addition, Geiger counter readings don’t tell you a thing about the type of radiation a person may be exposed to – whether it’s a fairly weak and short-lived isotope that doesn’t pose a health risk, a form of radioactive iodine that signals the need to take protective tablets, or a more sinister isotope, such as cesium-137, that can raise long-term health risks if it gets inside the body.

And this is the most worrisome form of contamination – internal contamination. The bad stuff on skin and clothes is easily washed off. But once radiactice particles get inside the body – through breathing in, but more importantly from ingestion – it can remain in tissues, possibly wreaking submicroscopic havoc, for a lifetime.

That’s why Thursday, Japanese authorities activated provisions of its Food Sanitation Act, which allows the government to test food for radioactive contamination and pull it from the market.

Experts say it was the Soviet Union’s failure to do that, for many weeks after the 1986 Chernobyl power plant disaster, that caused most of the health consequences – which continue to this day

NUCLEAR ENERGY: RADIATION VS. CONTAMINATION

A common misconception is the idea that exposure to radiation in turn makes someone radioactive. This is, usually, not the case. It’s important, then, to understand the differences between radiation, and radioactivity.

WHAT DOES IT MEAN TO BE RADIOACTIVE?

An atom is said to be “radioactive” if it is unstable due the excess of either energy or mass, and is therefore likely to decay at some point and give off radiation. A substance or material is said to be “radioactive” if it is made up of or contains a large quantity of a radioactive material. These radioactive materials, such as bananas, the uranium glaze in vintage fiestaware, or NORM generated in the process of natural gas exploration, give off radiation over time as the radioactive atoms in them decay.

Over time, as the number of unstable atoms decreases, the material becomes less radioactive. This time is measured by the “half life” of different radioactive elements. This is the amount of time it takes for half of the atoms in a given sample to decay and give off radiation. For example, carbon-14 has a half-life of 5730 years, so after that amount of time, a quantity of 100 atoms of C-14 would have turned into 50 C-14 atoms and 50 Nitrogen-14 atoms. Iridium-11, a radioactive isotope used in medicine as a tracer, has a half-life of 2.8 hours; whereas another isotope of iridium at the other end of the scale, iridium-115 has a half-life of 441 trillion years. It’s commonly held that a sample of radioactive material will be completely decayed after 7 half lives, though after that time there would still be about 0.78% left, which with a large enough starting sample would still be significant. For smaller samples like those typically used in medicine, though, it’s a good rule of thumb.

WHAT IS CONTAMINATION?

Put simply, radioactive contamination is just radioactive material somewhere it shouldn’t be. This could be anything from nuclear fallout from a dirty bomb (the whole purpose of which would be to disperse radioactive contaminant), to a lab worker splashing some of a radioactive solution on his pants and taking them home. The most common source of contamination is from mistakes or accidents in the production of radionuclides, like those used in the medical field.

Pripyat in Ukraine had to be abandoned after the Chernobyl accident due to the high amount of radioactive contamination

Contamination on or in a surface can be either “fixed” or “removable.” An example of fixed contamination, or contamination that isn’t able to be removed, would be in metal recycling: If a batch of recycled metal included something with radioactive material in it, the final product would have that radioactive material mixed in and permanently part of it. Removable contamination is, of course, removable, such as a loose powder or something that can be cleaned and safely disposed of. Disposal of radioactive waste can consist of reprocessing it for commercial use, though in some cases where this isn’t possible the best solution is burying it in concrete, rock, as this helps prevent the spread of the contamination any further.

DOES BEING EXPOSED TO RADIATION MAKE ME RADIOACTIVE?

Exposure to radiation does not immediately make a person radioactive. The only type of radiation that is capable of directly causing other material to become radioactive is neutron radiation, which is generally only found inside nuclear reactors or in a nuclear detonation. Anyone in those conditions is, put plainly, going to have bigger problems.

CT Scans and other routine medical procedures expose someone to radiation without leaving that person radioactive afterward

However, the ingestion of radioactive material does have the potential of making a person radioactive, at least on a temporary basis. This is the principle behind the medical use of many radioactive materials, as it aids in imaging, diagnosis, and other areas. Between the short half-lives of the elements involved and the body’s natural means of disposing of many radioactive elements, a person’s individual radioactivity is usually short-lived. However, certain types of contamination, depending on the isotopes involved and the availability of treatment, can become more permanently deposited in a person’s organs or bones.

EFFECTS OF RADIATION ON YOUR BODY :(

1) Hair

The losing of hair quickly and in clumps occurs with radiation exposure at 200 rems or higher.
(2) Brain

Since brain cells do not reproduce, they won’t be damaged directly unless the exposure is 5,000 rems or greater. Like the heart, radiation kills nerve cells and small blood vessels, and can cause seizures and immediate death.
(3) Thyroid

The certain body parts are more specifically affected by exposure to different types of radiation sources. The thyroid gland is susceptible to radioactive iodine. In sufficient amounts, radioactive iodine can destroy all or part of the thyroid. By taking potassium iodide, one can reduce the effects of exposure.
(4) Blood System

When a person is exposed to around 100 rems, the blood’s lymphocyte cell count will be reduced, leaving the victim more susceptible to infection. This is often refered to as mild radiation sickness. Early symptoms of radiation sickness mimic those of flu and may go unnoticed unless a blood count is done.According to data from Hiroshima and Nagaski, show that symptoms may persist for up to 10 years and may also have an increased long-term risk for leukemia and lymphoma.
(5) Heart

Intense exposure to radioactive material at 1,000 to 5,000 rems would do immediate damage to small blood vessels and probably cause heart failure and death directly.
(6) Gastrointestinal Tract

Radiation damage to the intestinal tract lining will cause nausea, bloody vomiting and diarrhea. This is occurs when the victim’s exposure is 200 rems or more. The radiation will begin to destroy the cells in the body that divide rapidly. These including blood, GI tract, reproductive and hair cells, and harms their DNA and RNA of surviving cells.
(7) Reproductive Tract

Because reproductive tract cells divide rapidly, these areas of the body can be damaged at rem levels as low as 200. Long-term, some radiation sickness victims will become sterile.

*Breaking* Wildfires are nearing the Chernobyl nuclear complex, creating a radioactive smoke, which is spreading across the region!

As if the pandemic wasn’t enough, a peculiar situation is now developing in Ukraine, where wildfires are nearing Chernobyl, the site of the nuclear disaster in 1986.

Fires have emerged around April 4th in the Chernobyl’s exclusion zone, the 30-kilometer area around the former nuclear reactor, where authorities have prohibited people from living. The fires were started by locals, burning the dry grasslands near the exclusion zone. The image below is a satellite capture from NASA/MODIS, showing the smoke from the fires on April 10th.

Wildfires in the region have spread to just over a mile from the defunct Chernobyl nuclear power plant and a disposal site for radioactive waste. More than 300 firefighters were battling the fires. The image below from FIRMS shows the hotspots detected by satellites in the past 24 hours, where we can see the fires nearing the nuclear complex of Chernobyl.

The main concern is not the fire reaching the reactor facilities or waste storage since they are not exposed directly to the fire. The problem is the burning of the forests and dry grasslands around the nuclear complex, since the area far around is still radioactive from the disaster in 1986. When fires burn the radioactive biomass, the particles that are released are also radioactive and can be carried by the winds, along with the smoke.

We created graphics from the NASA Geos-5 forecast system, which simulates the smoke from the Chernobyl fires, tracked as carbon monoxide loading. The first image is from yesterday, where the smoke was moving towards the north. The oncoming cold front has changed the wind direction which is now projected to send the smoke clouds (with potential radiation) towards the south and south-east. That would take the smoke over the capital of Kiev, and further towards the south into the Black Sea. The less likely (but plausible) scenario is, that the fires would spread even further, creating more radioactive smoke, which could spread west towards central Europe if the winds would be from the east. The current danger is limited to the surrounding areas and towards the Black Sea, but the situation will be monitored closely.

The radiation levels have already been measured to rise above the normal values, while the authorities in the capital are for now reporting normal values in Kiev. But that could change if the smoke with the radioactive particles would turn towards the south, directly over the city.

The fires have spread quite fast during the weekend, due to strong winds, making it very hard to contain it. Some relief has come tonight, as a cold front has brought rain to help fight the fires, and extinguishing some of the hotspots. Firefighters are on alert, to monitor the situation, as the weather provides aid with rainfall.
