Also basic translation for multiplication factor for the values on the reader equal to sensitivity of the measurement, x100 would mean its less sensitive reading a larger amount 50 100 150 and 200 rems and 1000 1500 is high enough to kill immediately, I'm guessing the time exposure and amount of radiation or the rate of exposure moves down in lethality taking a linear rate but that's just a guess
It should be rem as it is a US made instrument. The use of the rad means you know which type of radiation you are measuring as there is a conversion factor called the RBE or Relative Biological Effectiveness. The RBE is 1 for beta radiation, x-rays and gamma rays, so 1 rad = 1 rem. For alpha particles the RBE is 20, so 1 rem = 20 rad, as the alpha particle is more damaging to biological material. The Roentgen unit is the measure of ionisation of dry air, an older physics unit, so more appropriate for an ionisation counter.

Wow, this is fascinating to see. I really hope you used a Geiger counter before handling any of those items/taking them with you though
mR/hr.....?
What is the "R" unit? rem, rad, roentgen?

Thanks.
@@jayytee8062 Its Roentgen, exposure rate (expressed as milliroentgen per hour or mR/hr).
Is that check source harmful ? Should we let the geiger counter in our houses ?

With all these low yield war heads and ww3 talk this is great 👍🏾
