Attention , ce modéle est un CD V 700 révisé et remis en état par le vendeur eBay geoelectroncs ( George Dowell ) sur eBay USA ( vendu sous le nom de LENI ) . Si vous achetez ce modéle sans qu'il soit recalibré , la lecture du compteur sera fausse . Sinon pour le faire recalibrer vous devez l'envoyer au Texas au laboratoire KI4U qui dispose d'une source radioactive assé importante pour recalibrer les compteurs Geigers .
Common conversion rate is CPM x 10 = DPM because it is assumed that you can't measure every single disintegration occurring within a source with most ways of measuring.
Hello , Cont per minutes ( CPM ) is the number of desintegrations in a minute ( 60 seconds ) . In Europe we count desintegrations by seconds , the unit is the " Becquerel " . Bye , Fred .
Nice demonstration!

Good thing they didn't use radium paint to paint the counter.

30s,40s,50s era paint had urainium in it

@remington12799 The only paint was for the Fiestaware. Besides that, they used some in that yellow-green glass.

You're supposed to start from the highest scale on any galvanometer.

counts per minute = decays per minute ?

Smacking the needle around?

You're supposed to start from the highest scale, not the lowest. Doing that will lead to constant galvanometer recalibration.
