RadCast West Coast Soil Radiation Testing

RadCast West Coast Soil Radiation Testing

RadCast is now conducting a very extensive study on radiation in West Coast organic garden soils. We know that the West Coast was hit hard right after Fukushima blew on 311 but what we don’t know is how much radiation is still in our soil from that time.

Fukushima is an ongoing 24/7 catastrophe; how will it affect the food supply from our home grown foods? Has it already affected our food supply? No one knows because no government agency has tested the soil and food supply to find out. RadCast is the first.

After we complete Phase 1 which is the collection of soil samples along the West Coast, we go back for Phase 2 which is the collection of vegetation grown on the areas where we took soil samples.

All results will be posted here on this page by city or town name. You will see graphs and data. While we will not be making commentary on our findings, we will be listing all radionuclides present in the samples and all of the data that we uncover. RadCast believes that any amount of ionizing radiation in the food supply has always the potential to be dangerous to your health.

If you have questions about our study, please email us at info@radcast.org. If you would like to make a donation to RadCast to help offset our costs for this project, please go to the home page and click on the donation button. We thank you for your interest in our project.

Our Gamma Spectrometer is an 1100A.

Sweet Home is in a river valley in the foot hills of the Oregon Cascades, just east of the Willamette Vally. The region’s geology is dominated by volcanic phenomena, starting 52 million years before present, until now. The active volcanic zone has shifted just 40 to 70 miles to our east. The lavas and volcanic ashes that make up the soil are mineral rich. Amongst these minerals, the thorium (Th 234) evident in these spectra has a magma source brought to the surface by volcanic processes. The combined spectra are from four separate  locations in the valley, miles apart. The thorium 234 peaks are most prominent. These peaks high light a radon concern in the Sweet Home area.
