Hello,

I've just received my GMC-320 Plus ordered a few days ago on Amazon. In the box, I got a little plastic card titled "Nuclear Radiation Safety Guide", with values in CPM, ySv/h and mR/h, and the corresponding action to take.

What is really strange is the >2000CPM line corresponds to >500ySv/h. Which seems way off from what the GMC-320 would measure, because the GMC-320 gives a value of 10-14ySv/h for around 2000CPM (I don't remember the exact value). Which is much less than the 500ySv/hr on the card.

So... is the card made for a different geiger tube ? Maybe a pancake tube which is way more sensitive and big ?

What value is more "realistic" to the action written besides it. The CPM column ? The ySv/h column ?

Those value between columns are not directly mapped by value. Those are reading examples.

However, to make more sense, it should mapped by conversion rate.
