    Fell into contaminated water and swallowed some. Ended up with a 300 count per minute of measurement (I have no frame of reference for this but it seems to be a tipping point for medical evaluation).

      CPM is nearly useless because it doesn’t tell you what type of radiation… But for couple generic references, background radiation is usually about 60 cpm, and an international flight can be about 800 cpm.

      So again, cpm is a useless metric without other context. It’s just the raw number of “hits” on the detector from any source it detects. Some particles are basically harmless, others not so much.
