Yes they are not showing any DAC readings. ( Derived air concentration (DAC)
The concentration of radioactive material in air that will result in an annual limit of intake if an individual breathes that air for a year.
I looked at that clip again since i cannot capture it it looked like 100 on reading of that girl. but I dont know the scale of the meter , I assume in
MV / millisieverts per hour .
I get 100 mSv/h, this is again is on the low side but still high for a short time exposure for that girl on NHK.
even if this reading is between 40 -50 Msv/h it's still a good shot of radiation for a short time.
This is about the exposue of a full body scan,one time. From what I remember from nuke weps school for Msv/ Hr basis is that that potassium iodide
pills should be distributed when the likely absorbed dose of radioactivity is 100 Msv/hr assuming that this the rate of exposure of this girl on NHK
live feed.
Highest reported radiation beside reactor 3 at Fukushima I: 400 mSv/hr[9]
Highest reported radiation at reactor 2, Fukushima I: 8 mSv/hr
I used this old scale conversion:
1 Sv = 1000 mSv (millisieverts) = 1,000,000 μSv (microsieverts) = 100 rem = 100,000 mrem (millirem)
1 mSv = 100 mrem = 0.1 rem
1 μSv = 0.1 mrem
1 rem = 0.01 Sv = 10 mSv
1 mrem = 0.00001 Sv = 0.01 mSv = 10 μSv
Anyone know the scale their using ?
curie
sievert
becquerel
coulomb/kilogram (C/kg)
gray
rad
rem
roentgen (R)
