Sustained Radiation Spike in Washington.Video.

Air monitoring stations, Washington State Department of Health, April 4, 2011:

…The chart shows radiations measures known as “gross beta,” a term that refers to all radioactive materials that emit beta radiation. Gross beta measurements are used because they give us the fastest indication of any change in radiation levels. They’re measured in “counts per minute.” …

Read the report here.

Notice the average daily reading for Richland, WA on March 31. (Richland was one of just two cities in the U.S. where the E.P.A. found radioactive particles in drinking water)

 

RICHLAND — The Environmental Protection Agency (EPA) has found radiation in Richland tap water. Only two spots in the whole country where it was found: Richland and Boise. Should you be worried? No scare tactics here, KEPR is digging for facts.

It’s a frightening headline at face value: knowing contamination from Japan has finally made its way here. Action News looks at the reality behind the radiation results.

On the surface it sounds bad, of the 50 cities in the country the feds tested, only two popped up with trace amounts of radiation in drinking water and one of those is Richland.

But how much radiation are we actually talking about? KEPR discovered one of the foremost radiation specialists in the nation lives in the Tri-Cities.

“0.23 picocuries per liter doesn’t scare me very much. Because it is so very, very little,” said Antone Brooks.

Brooks knows what he’s talking about, he’s devoted his life to finding out how nuclear fallout spreads.

The EPA says a baby would have to drink 7,000 liters to get a dose of radiation equal to what we’re exposed to in the world every day.

So why did Richland test positive for Iodine-131? KEPR asked the EPA speaking with headquarters through a media conference call.

A spokesperson says they are looking at weather patterns as a possibility of why it turned up in Boise and Richland.

Radioactivity Found in US.

Low levels of radioactive iodine linked to the nuclear disaster in Japan were detected in a sample of rainwater in Massachusetts, state health officials announced yesterday.

The concentration of radioiodine-131 found in the sample is very low and did not affect the health of the state’s drinking-water supplies, said John Auerbach, commissioner of the Department of Public Health.

The rain sample was taken during the past week in Boston as part of regular monitoring by the US Environmental Protection Agency. No detectable increases in radiation were discovered in the air that was tested in the same location where the rainwater was collected, Auerbach said at a press conference yesterday at the William A. Hinton State Laboratory Institute in Jamaica Plain.

Japan Seawater Radiation 1250 times more.

The level of radioactive iodine detected in seawater near the Fukushima No. 1 nuclear power plant was 1,250 times above the maximum level allowable, the Nuclear and Industrial Safety Agency said Saturday, suggesting contamination from the reactors is spreading.

Meanwhile, plant operator Tokyo Electric Power Co. turned on the lights in the control room of the No. 2 reactor the same day, and was analyzing and trying to remove pools of water containing radioactive materials in the turbine buildings of reactors 1 to 3.

The iodine-131 in the seawater was detected at 8:30 a.m. Friday, about 330 meters south of the plant’s drain outlets. Previously, the highest amount recorded was about 100 times above the permitted level.

If a person drank 500 ml of water containing the newly detected level of contamination, it would be the equivalent of 1 millisievert of radiation, or the average dosage one is exposed to annually, the NISA said.

“It is a substantial amount,” NISA spokesman Hidehiko Nishiyama told a news conference.

But he also stressed there is “no immediate risk to public health,” as the changing tides will dilute the iodine-131, and its half-life, or the amount of time it takes for it to lose half its radioactivity, is only eight days.

Nishiyama said the high concentration was perhaps caused by airborne radiation that contaminated the seawater, or contaminated water from the plant that flowed out to sea.

Tepco said early Saturday that it had detected a radiation reading of 200 millisieverts per hour in a pool of water in the No. 1 reactor’s turbine building on March 18 and failed to notify workers, but later denied that a radiation level that high was found.

“If we had warned them, we may have been able to avoid having workers (at the No. 3 reactor) exposed to radiation,” a Tepco official said.

Water Contamination /Health Issues in Japan.

In natural disasters on March 18, 2011 at 00:22

In 80 km distance from nuclear power plant the increased radiation level was detected in  drinking water.
The representatives of nuclear department said the chemical substances and cesium detected in the water are not dangerous for  life. The contamination of water with radiation is very low they reported. The experts say the contamination of the water was caused by the damage of electricity station.
After natural disasters without drinking water are left 1.6 mn people. Japanese government sent to them 300 cars with water. The number of died exceeds 10 000.

Japan Nuclear Crisis Raises Food, Water Anxieties

by Gretchen Goetz | Mar 17, 2011

Fear is spreading faster than contamination following leaks of radioactive material at the damaged nuclear power plant in Japan. While the situation is changing rapidly, so far any potential threat to food, water and air safety remains minimal.
Food Supply
Japan has one of the world’s best food safety systems and imports more food than it exports, but some nations have expressed concerns that foods produced in Japan might be contaminated with radioactive material. Asian countries surrounding Japan are testing food imports. Australia and the European Union announced that they would be conducting tests as well, and Italy has put a temporary ban on all food coming from Japan.
However, as of now, there is little reason to worry about the safety of Japanese food products, according to Dr. Richard Morin, professor of Radiologic Physics and Chairman of the American College of Radiology’s Safety Committee.
“From what we know right now, most of the radioactive material has blown out into the atmosphere east of Japan, and as long as that continues to be the case, there won’t be much contamination on the island of Japan. That would lessen the alarm about foodstuffs,” he says.
And the likelihood is slim that some foods will be coming from Japan in the near future.  Many fishing fleets there are in ruins following tsunami.
Water Supply


While tiny amounts of radiation were detected in the water supply in the area surrounding the plant, according to Fuji TV Wednesday morning, amounts were too low to be immediately harmful to human health. Officials will continue to monitor the situation.
Preventative Measures: Potassium Iodide
Sales of potassium iodide pills, taken to combat the negative effects of radiation, have skyrocketed in the United States in the past week, as people worry that radiation will spread through the atmosphere from Japan to the West Coast.
Potassium Iodide works by filling the thyroid with a non-harmful type of iodine, so that Iodine-131, the harmful element arising from nuclear radiation, cannot be absorbed into the thyroid when ingested. The pill will work to prevent Iodide-131 ingested in any way, via food, air or water.
While Morin says potassium iodide is indeed effective, he says the current nuclear leak does not pose a serious enough threat to warrant taking these pills.
“It would be most likely that exposure to the thyroid from any Iodine-131 that would make it across the ocean would probably produce a radiation effect not a whole lot different than if you flew from Seattle to Boston,” he says.
He says that, at current levels, most of the radio nuclides containing this harmful element will not make it to the United States, but will drop out of the atmosphere into the ocean or be dispersed by the prevailing winds.
“The concentration, that is the amount of radioactivity per cubic foot of air, goes down dramatically as it travels.”
