Quote:Release of Radioactive Material from Fk-1

Occasionally sudden peaks (spikes) appear on a number of posts, near and far. If time sequences are carefully taken account of, it seems, they could show the flow of a plume. Such a plume flow was seen throughout Japan on April 14, 2015. Spike phenomena occurred on April 8/9 and May 16, 2015, as well.

These are recorded on the monitoring posts, but many places are not covered by monitoring posts, where much higher radiation levels have been recorded; i.e., “hot spots”. Recently reported examples were: 1.23 μSv/hr in western Tokyo on July 23, 2.92 μSv/hr in Saitama on July 25, 4.8 μSv/hr in Iwaki (30 km south of Fk-1) on Aug. 2 9.

9 This kind of data is regularly reported by activists/organizations on the internet; its accuracy cannot be ascertained. It can be said only that such high spots likely exist.

Each time there are spikes on monitors, the government attributes such a phenomenon to a “malfunctioning monitor”, and shuts down such posts, until the readings return to normal (regular) levels. It is rather strange that a number of monitoring posts (all across Japan) go out of order simultaneously or rather in sequence. This phenomenon indicates that sudden releases of radiation are still happening occasionally, but how often, on what scale, and their causes are not known.

Some of these dates are already in albums at HorseCam , dates when the webcams were full of sparks and smoke.
