Porterblog video dated Sunday October 23 describes recent detection of Iodine-133 in St Loius rain-water and compares it with detection of Neptunium-239 in rain-water on October 10.

The most recent detection is of Iodine-133 and Zenon-133.

Potrblog states that the exposure levels in the precipitation are 2.76 millirem an hour
(27.6 microsieverts an hour according to calculator I found here http://online.unitconverterpro.com/unit-conversion/convert-group/convert.php?cat=radiation---dose-equivalent)

Potrblog states that the “Troubling thing is we were not warned

There are things to do to protect against iodine fallout

He notes that since the Iodine 133 has a 20 hour half life, there was a lot coming from Fukushima

EPA has been giving no data on iodine detection since March

Rain concentrates fallout


Potrblog describes the radioactive fallout cycle of first Neptunium 239 (Oct 10) and then the Iodine-133 (last week) that he believes derives from the on-off criticality of the corium in the ground water.

The Criticality Cycle stems from corium in ground water, which is creating a cycle of a neutron feast and neutron famine.

High Levels of criticality produce Neutron feast: Neutron bombardment creating neptunium-239 that decays into plutonium-239.

Something happens to change conditions leading to a neutron famine.

Neutron Famine: Iodine and zenon then get produced. Iodine-133 and zenon-133 absorb neutrons and thereby temporarily reduces intensity of criticality.

Alternating cycle of neutron feast and neutron famine explains the fallout Potrblog is detecting in St Louis.

He says that it is possible that this on-off cycle could produce a large explosion but says he lacks access to the data and the modeling to allow him to predict the likelihood of an explosion.

When is it risk mitigating to have an explosion to “de-criticalize” what is happening there he asks again?

My opinion is that the Potrblog team knows what they are talking about. This video uses data from the jet stream, the EPA, and detailed mathematical analysis of decay chains to support its claims and encourages viewers to offer alternative interpretations of the data.
