On September 24, a test was performed to measure surface radiation contamination accumulated on the surface of an air conditioning filter that had been in service for 90 days.

The filter tested was an Aprilaire Model 2200 and all measurements were determined using  an Inspector Alert Surface radiation contamination monitor, Model AI-V2.

The first 10 minute test was performed on a brand new filter to determine the particle decay rate (CPM) on a surface not contaminated by prior service as an air conditioning filter.

A second 10 minute test was performed on a filter surface following 90 days of normal operation from mid-June through Mid-September, 2015 .

The new filter measured a 10 minute rate of 308 counts or 31 counts per minute while the used filter reported a 10 minute rate of 714 counts or 71 counts per minute – more than twice the decay rate of the new, uncontaminated filter.

Although 71 CPM is under the radiation warning rate of 100 CPM the test reveals hidden radioactive contamination can be insideously introduced into the breathable household atmosphere.

California Detects Radiation in Rainwater


As reported in the article, “High Radiation Detected in L.A. Rain” hot rain was detacted in the western Los Angeles basin multiple times with the highest registering 3.3 times background levels. The California Highway Patrol considers any substance radiating more than three times background hot enough to trip its Hazardous Materials protocols. Those emergency measures include suiting up personnel in impermeable outfits with ventilators.

Those precautions were not evident in the greater Los Angeles as the storm drenched thousands of people caught unawares of the impending storm. High levels of beta radiation in rain are especially of concern when children and pregnant women are exposed to the hot water which can cause blood cancers, including leukemia, and a host of ailments introduced courtesy of the Atomic Age.


  1. Harold, do you have any coal fired power plants or coal ash ponds located near you? Coal fly ash is a potential radioactive source.

    This study [Publication Date (Web): September 2, 2015] lays the groundwork for future research related to the environmental and human health implications of coal combustion residual (CCR) disposal and accidental release to the environment in the context of this elevated radioactivity.

    Naturally Occurring Radioactive Materials in Coals and Coal Combustion Residuals in the United States

    • Yes, I’m aware of the possible radiation sources, including radon and electronic equipment inside the home. Most cities do have coal burning plants in their district. Gainesville happens to have a coal and woody biomass plant located about 12 miles due north of the City. This location is not favorable for blowing smoke due south since the trade winds are from SE to NW except during a few days in the winter. —- In another case — When rainwater samples tested at my home showed aluminum the local environmental protection office suggested the aluminum was coming from the coal plant. I have performed 2 rainwater samples for radiation with no detectable increase in CPM. I also performed a test on tap water that was negative for a 10 minute scan.

  2. J. Marvin Herndon PH.D. has just released an error-corrected version of his article, Evidence of Coal-Fly-Ash Toxic Chemical Geoengineering in the Troposphere: Consequences for Public Health. Please read it in full here:

    Dr. Herndon identifies 8 elements in rainwater samples and 14 elements in HEPA dust air filter samples which are essentially identical to leachate and un-leached coal fly ash with a 99% confidence interval.

  3. EPA unveils first-ever regulations for coal ash

    But the rule does not allow for any federal enforcement, relying instead on states and on lawsuits brought by the public. It also does not cover ash storage sites at plants that have been closed.

    The EPA also decided not to go as far as classifying coal ash as hazardous, saving utilities billions of dollars in compliance costs and disappointing environmentalists, who said that move would provide the best possible protection for waterways, wildlife and groundwater.

    Coal ash can contain substances like chromium, arsenic, mercury and lead; it is the second most common waste in the country, behind household trash.

    Under the new standards, coal ash will be subject to disposal rules similar to trash, under Subtitle D of the Resources Recovery and Conservation Act.

    Environmentalists criticized the rule as too weak. Greens and health advocates had pushed for hazardous waste standards, arguing that the toxic minerals in coal ash make it the obvious conclusion.

    “How could EPA conclude that coal ash, which is loaded with carcinogens including arsenic, cadmium, and chromium, is not a hazardous waste?” Marc Yaggi, executive director of the Waterkeeper Alliance, said in a statement.

    “These toxins are contaminating the land and water around hundreds of coal ash dumps across the country. Today’s rule falls far short of what is needed to protect communities and ensure clean water for all Americans.”

  4. Radioactive Contaminants Found in Coal Ash
    Wednesday, September 2, 2015

    “Until now, metals and contaminants such as selenium and arsenic have been the major known contaminants of concern in coal ash,” said Avner Vengosh, professor of geochemistry and water quality at Duke’s Nicholas School of the Environment. “This study raises the possibility we should also be looking for radioactive elements, such as radium isotopes and lead-210, and including them in our monitoring efforts.”

    Radium isotopes and lead-210 occur naturally in coal as chemical by-products of its uranium and thorium content. Vengosh’s research team revealed that when the coal is burned, the radium isotopes become concentrated in the coal ash residues, and the lead-210 becomes chemically volatile and reattaches itself to tiny particles of fly ash. This causes additional enrichment of radioactivity in the fly ash.

    “Radioactive radium and lead-210 ends up concentrated in these tiny particles of fly ash, which though individually small, collectively comprise the largest volume of coal ash waste going into holding ponds and landfills,” said Nancy Lauer, a Ph.D. student in Vengosh’s lab who was lead author of the study.

    The study comes as the U.S. Environmental Protection Agency’s first-ever regulations on coal ash disposal are set to go into effect in October.

    Currently, coal ash disposal sites are not monitored for radioactivity, Vengosh noted, “so we don’t know how much of these contaminants are released to the environment, and how they might affect human health in areas where coal ash ponds and landfills are leaking. Our study opens the door for future evaluation of this potential risk.”

    Smokestack scrubbers installed at U.S. power plants keep these contaminants from escaping into the air when the coal is burned, he stressed. But if the contaminated coal ash is spilled, or if effluents leak from ponds or landfills, it may pose a hazard.

    “Because of the tiny size of the fly ash particles, they are much more likely to be suspended in air if they are disposed in a dry form. People breathing this air may face increased risks, particularly since tiny particles tend to be more enriched in radioactivity,” Lauer said.

    “I think we have to treat this seriously,” explained Avner Vengosh PhD. The Duke University geochemistry professor says coal ash may pose a bigger risk than first thought.

    “This should be defined as a hazardous waste and therefore should be treated as such,” Vengosh said.

    The peer-reviewed study says they’ve concluded that coal ash contains radioactive contamination at levels up to10 times higher than unburned coal.

    Vengosh admits the levels of radiation are very low and are naturally occurring.

    “If you compare it to the average soil in the United States it’s about 5 times higher,” he explained. But he says the radioactive materials can still pose environmental and health risks.

    He says what makes it a risk coal ash’s tiny particle size and storage practices, making it more likely to reach the environment.

    “There is the risk of emission into the atmosphere or emission to the groundwater when we have spills or leaking of coal ash ponds,” Vengosh said.

    Vengosh says the isotopic ratios of the radioactive material found in coal ash are unique to the coal it’s burned from. This means researchers may now use it almost as a fingerprint, to determine the source of any contamination.
