Japan Confirms Plutonium in Soil Samples at Fukushima Daiichi.

After taking soil samples at the Fukushima Daiichi nuclear power plant, Japanese authorities today confirmed finding traces of plutonium that most likely resulted from the nuclear accident there. The Nuclear and Industrial Safety Agency told the IAEA that the Tokyo Electric Power Company (TEPCO) had found concentrations of plutonium in two of five soil samples.

Traces of plutonium are not uncommon in soil because they were deposited worldwide during the atmospheric nuclear testing era. However, the isotopic composition of the plutonium found at Fukushima Daiichi suggests the material came from the reactor site, according to TEPCO officials. Still, the quantity of plutonium found does not exceed background levels tracked by Japan’s Ministry of Education, Culture, Sports, Science and Technology over the past 30 years.


Prior to 1945 plutonium was present as a contributor to “background”. The terminology is that of “normalisation.”

Less than Background is the same old inducement to conclude the illogical. In fact human contribution adds to background. The contribution is added to background to result in an increased potential individual dose. The term “less than Background” seems to be a trigger which may induce a pleasant feeling conditioned reflex in popultions. Slightly changing the wording does not change the reflex.

Conditioned Reflex.
Pavlov’s main area of research throughout his scientific career was on the digestive process, which brought on a series of experiments exploring the correlation between the nervous system and the autonomic functions of the body. Pavlov experimented with dogs, studying the relationship between salivation and digestion. By applying stimuli to the animals in a variety of ways, using sound, visual, and tactile stimulation, he was able to make the animals salivate whether they were in the presence of food or not; a phenomenon he called the conditioned reflex.
