Co si predstavujete pood pojmem kalibrace a nastavenio
Mate GM trubici u ktetre znate parametry, na ni privedete ji odpovidajici
napeti a dal je to jiz jen o tom, ze prulet castice ionizuje a vy ten prulet
slysite.
Pokud neznate parametry GM trubice tak je to problem, bezne GM poznaji tvrde
gama zareni a beta s energii pres 2,5MeV tedy nic co je vhodne pro takove to
domaci jaderne badani.
Beta zarice najdete v nekterych detektorech, ale ty nemaji 2.5MeV. Nektere
GM excituje i RTG zareni to pak lze nastrelit na zubarskem RTG, staci RTG,
trocha alobalu a trocha matematiky :-)

GM neni primarne merici cidlo, je to spise detektor, pokud to tika trochu o
nic nejde, kdyz hoodle jak zdrhej, nic vic od toho necekejte, pokud chcete
merit treba kosmicke zareni tak to chce jine cidlo, za jine penize.

KN




 
will detect gamma radiation, and usually beta radiation above about 2.5 MeV.

Dobré dopoledne,
chci se zeptat jestli někdo z vás doma bastlil geigerův čítač. Vyzkoušel 
jsem cca 3 zapojení a vykazují rozdílné výsledky.
Proto hledám rozumný způsob jak to bezpečně ověřit a nastavit.
