Hi,

This weekend I left my GMC320+ 4.06 in the car park of a shopping area and came back 6 hrs later to a maximum of 26k CPM
It lasted for about an hour, depleting.
CSV coming soon!

At a conversion rate of 0.005 that's about 132uSv/h?
According to my chart that's "danger, risk of damage, leave area"


Is this likely to be a fault or should I be worried?

It would be good if the unit logged uSv/h with CPM in the bin/CSV or is that meaningless if you recalibrate? Is that something undocumented we can request with RFC1201?

I do not know what exactly was wrong. But it was an abnormal high reading.

If you have moved location at that period but the reading did not change, then it can be a hardware failure at that time.

I suggest you to let unit run for a period and see if it happened again. If the reading is true, then it should be repeatable.

The event had stopped before I got back to my car. The unit was stationary.

My friend is a pilot, and is going to fly me around the area soon too see if there's anything in the atmosphere! Any excuse to fly!
