Arnie Gundersen: More on "Hot Particles" from the Fukushima fallout that reached the US

Arnie Gundersen's latest video talks about "hot particles".

========
Original estimates of xenon and krypton releases remain the same, but a TEPCO recalculation shows dramatic increases in the release of hot particles. This confirms the results of air filter monitoring by independent scientists. Fairewinds' Arnie Gundersen explains how hot particles may react in mammals while escaping traditional detection. Reports of a metallic taste in the mouth, such as those now being reported in Japan and on the west coast, are a telltale sign of radiation exposure.

Hot particle
From Wikipedia, the free encyclopedia


A hot particle is a small, highly radioactive object, with significant content of radionuclides. Because radioactivity can be inherent to a substance or induced, and there are many initial sources of radioactivity, hot particles can originate from a multitude of sources.

Hot particles present significant health hazard when ingested or entered the body by other means. They are several orders of magnitude more dangerous than the same amount of radiation emitted from a large source over the whole body because if ingested or inhaled, they do damage to cells at close proximity. <1><2>

The size of hot particles contained in nuclear fallout ranges from 10 nanometers to 20 micrometers for the worldwide fallout; particles present in local fallout are significantly larger (100 micrometers to several millimeters).

Hot particles can consist of tiny specks (~10 micrometers sized) of nuclear fuel (so-called fuel fleas, due to their tendency to become electrically charged and then jump from surface to surface), or of other material activated by exposure to neutron radiation.

Hot particles can be identified by a Geiger counter, or by autoradiography. Their age and origin can be determined by their isotopic signature.
Origin

Radiation can spread from a more radioactive substance to a less radioactive one by the processes of neutron activation and photodisintegration; this induced radioactivity increases the potential number of hot particle sources.

Hot particles released into the environment may originate in nuclear reactors. The Chernobyl disaster was a major source of hot particles, as the core of the reactor was breached, but hot particles are found near undamaged nuclear reactors as well.<3>

as some in this forum would have us believe.

He lays it out pretty darn straight. It's very depressing to learn this after the fact but I believe his bigger goal is to try to help people in Japan and avoid this kind of catastrophe in the USA.

Plus, there were those of us giving the warnings, but most were unconcerned.

It's just not a great idea to be drinking milk from Seattle right now..

A cheap attempt to make a buck by terrorizing people over getting less of a radiation dose than you do walking from your front door to your car on a sunny day.

Arnie is not making bank appearing on Cnn every few weeks.
