The New York Times ran a WIPP story today, NUCLEAR WASTE REPOSITORY SET TO REOPEN AFTER LEAK, New York Times — February 26, 2014, By Matthew L. Wald
This is a good example of what is known, what is being said, and what is not being said.
1. One shaft has a filter with a monitor and three don’t. The article, and many others, quotes a WIPP press release,
But late on Feb. 14, at an hour when no one was in the mine, an air monitor indicated the presence of radioactive contamination. An automated system cut off most of the ventilation and routed the exhaust through filters that are supposed to capture 99.97 percent of all contamination, turning off fans and changing the air flow, in less than one minute.
At WIPP, there are 4 ways for air to get to the surface – the Exhaust Shaft, the Salt Shaft, the Air Intake Shaft, and the Waste Handling Shaft. When radioactive contamination is detected, airflow is directed to the Exhaust Shaft as its filter is put into place. This shaft has the only filter and monitors on any of the shafts. WIPP officials claim that it was a monitor in Panel 7 that detected radiation and set into action the sending of all the air to the Exhaust Shaft. The Panel 7 monitor is around 2000 feet from the shafts. This means that the WIPP officials were relying on any contamination to set off the monitor before any contamination went up a shaft. We need a layout of the monitors, and if they were working, in the underground.
2. “Safe levels” of radioactivity? The article quotes a WIPP monitor,
“For someone living in town, I would say the dose was probably zero,” Russell Hardy, director of the Carlsbad Environmental Monitoring and Research Center, an independent monitoring organization that is part of New Mexico State University, said in a telephone interview Tuesday. He said that the event would not add to background levels of radiation — including bomb fallout — any more than an eyedropper full of water would contribute to the rise in the level of the Pacific Ocean.
Seriously, an eyedropper in the Pacific? I had to look it up –
There are over 70 cubic million miles in the Pacific Ocean. Meaning there are 188,000,000,000,000,000,000 gallons in the pacific ocean. That is 187 quintillion gallons.
No problem, unless you eat the fish that drank that drop. Anyway, I don’t believe anyone knows how much radiation was released. The preliminary results are based on a ridiculously small number of air samples. The official projections are based on the implication that the samples represent the maximum contamination, which is unlikely.
3. Then, it was explained how to get dosed –
Even in the desert, the danger to humans was small, the mine’s operators said. The highest reading from the monitors indicated that a person could have inhaled radioactive material that would emit a dose, over the person’s lifetime, of 3.4 millirem, an amount roughly equal to three days of natural background radiation. But to get the dose, the person would have had to stand for hours in the desert, on the downwind side of the plant.
Again, the official projections are based on the implication that the samples represent the maximum contamination, which is unlikely. We await the many soil samples that will shed light on the actual amounts.
