What does the reading on a Geiger meter equate to in physical effects?

Question

I know 0.2 isn’t very worrisome but 1.5 is. What is the difference in the physical effects between these readings and readings 2.0+?

Thanks 🙂

Answer 1

It’s usually sieverts if it is measuring dose, .2 would be worrying. 2+ would cause immediate radiation sickness. If it is mSv then neither is too troubling. If it isn’t measuring dose it is measuring instances of ionizing radiation in a set time period, minutes or seconds
