I want to try to contribute to this topic, by debunking any false assumptions and speculation on the instrumentation's readings being off, as a
previous posted has speculated.
The instruments all have their own design, but the standard is that the reading picked up by the circuit board is an instantaneous count/value at the
time of reading, which by all rational thoughts and observable physics, the amount of radiation hitting the sensor will vary. Therefore, in order to
ascertain a usable figure, as a rate of radiation per hour, multiple readings are taken and averaged.
For instance, some equipment may see a reading of 17, 3, 88, 23, 7, 5,9 (no these are not the lotto numbers), if the device shows 88 or 5 uSv (or any
scale) per hour, it is obviously going to be wrong, it must estimate based on the last X number of readings, what the rate for the hour will be.
You will see this with very cheap and poorly designed circuit boards, such as those used in circuits 101 classes, where an LCD will display a value
one second, instantly change to some other value. If you took any form of circuits course, you would know that a modification to the circuit diagram
is needed to "average" values in order to normalize the reading.
Therefore, I see absolutely no proof based on my limited knowledge, that the readings are inaccurate. I would speculate that the area where the
video(s) are filmed may be subjected to a higher amount of radioactive rain water than other parts of tokyo proper. I personally have not seen
anything significant in my section of CONUS, but if I were in Tokyo seeing those numbers, I wouldn't be living there for very long myself.
