Normal background levels are generally between 10 and 40 or even up to like 60 or so. That's pretty normal although fluctuations are expected because
of various reasons *many many various reasons*.
Generally an *alert* or warning level would be when it surpasses a count of 120, because at that point you have to realize there is a source of
radiation being detected that is generally out of the normal circumstances. Some places always show high readings though, and although people say
thats "normal and safe" I wouldn't be living there. For example Billings Montana generally has a very high radiation count compared to most other
locations.
There are 1000s of things that could cause radiation meters to have higher than average readings. And sadly most of the detection equipment is not
capable of determining the source of those readings.
But in a general sense, when the cpm goes above 120, we need to start looking for answers and figuring out what the cause of that radiation may be.
Just to play it safe you know.
The odds of the 1280 reading in NY being from Japan are exceptionally low, and I would consider it very unlikely. The reason is because the
surrounding other meters are showing generally normal readings (although perhaps slightly higher than pre-Japan quake, we can debate that).
But such a high reading without the context of the other meters nearby showing high readings, we are going to have to consider this a "localized
source" rather than a global or regional event.
