East Los Angeles checks in with 10 minute averages at 5:15pm
External 49 cpm- normal for this area.
Internal 39 cpm- normal
External dose 12uR/h-normal for this area.
External 1 hour ambient dose
13 microrems per hour (uR/h) +/-10%
All normal readings on the east side
External 47 cpm-normal
External gamma 1 hour integrate 13 uR/h-normal
After various 1 hour internal and external tests we established a normal background baseline of 12-14 uR/h for the East Los Angeles area. This is good to keep in mind since a rise in gamma at this location would indicate something is going on.

Hello fellow reporters. We will be back soon reporting levels from the east side of los angeles. We are awaiting our johnston gsm 500 survey meter to return from a fresh calibration. We also added an energy compensated probe in order to give more accurate ambient dose readings from a range of 5 uR/h up to 200 mR/r this would apply to gamma only.we will also report in counts per minute (CPM)with the sesnitive pancake probe. Stay tuned for count readings from the east side of town.

Active rain in east los Angeles.
Here are the readings for this morning shower. These are 10 minute averages
Interior background-45 cpm-normal
Car window wipe test rain sample 210 cpm. Probe in plastic bag so only looking at beta and gamma rays. Looks like radon progeny on the east side. This test was conducted at 10:30am.
[Editor: Rain progeny which does affect East Los Angeles can measure up to one to two times background. This sample is 3.67 times background HIGHER and should be considered HOT.]
