i have 7 dosimeter pens and the charger for them
two are 0 to 200 roentgens scale
two are 0 to 600 roentgens scale
three 0 to 200 milliroentgens
with a simple string system i can use the 0 to 600 pens to check the outside radiation levels by running one out side for a timed exposure then pull
it back inside to read and recharge
the charger i have is a old navy type that does not need batteries.
try that with your homemade system.
