Bob Nichols of Veterans Today Is OverStating Radiation Levels by Falsely Comparing Gamma Scint Readings to Geiger Readings

stock here--One writer is catching people's attention by point out radiation levels that are hundreds of times worse "than normal".   Trouble is, he is falsely reporting and comparing apples to buffalo burgers.

I duplicated Mr Nichols recent values by extracting EPA data for 20160731 to 20160813
for the first 5 in his post,
the date time stamp is the ending of the measurement cycle UTC zone
added gamma ranges 4 and 5
ME: Portland; 1838; found on 2016-08-01 10:38:27
CO: Colorado Springs; 1658 ( not found, value found by adding gamma 4,5,8 ) on 2016-08-13 13:23:20
when adding only g4,5 the peak is 1533 on 2016-08-03 13:34:33
IL: Champaign; 1573; found on 2016-08-11 11:38:15
AR: Little Rock; 1571; found on 2016-08-07 22:55:04
NM: Navaho Lake; 1564; found on 2016-08-04 02:32:34
EPA gamma energy ranges ( keV )
2 100-200
3 200-400
4 400-600
5 600-800
6 800-1000
7 1000-1400
8 1400-1800
9 1800-2200
10 2200-2800 ( no longer available )
So range 5 is Cesium137 ( 662 keV ) and Cesium 134 ( 604 keV and 795 keV )
I don't know what range 4 is.
Others I know of
I131 is at 190 keV (range 2 )
Co60 is at 1170 keV and 1330 keV ( range 7 )
K40 is at 1460 keV ( range 8 )

  • Great work, I knew he was taking some fraction of total gamma spectrum.
    nevertheless, he then tries to compare it to a standard CPM of a Geiger counter. That is poor reporting, and makes a strawman of us.
