Meaningful alarm thresholds for Germany or in general

[thei85]

Hi, I know this might not be the perfect forum for my question, but I’m asking for help anyway.

I’ve just flashed my F-Nirsi GC-03 with Radpro 3.1.1—it’s a truly excellent upgrade.

Now I’m wondering what alarm settings I should use for Germany regarding the count rate warning, count rate alarm, dose warning, and dose alarm. Should I just stick with the default values?

I realize the GC-03 isn't a professional-grade Geiger counter; I use the device out of personal interest in my daily life.

What dead-time compensation setting should be used for the M4011 tube?

Also, regarding source compensation, what is the difference between "None (Cs-137)" and "Background radiation"?

• Start by reading the Ionizing Radiation Field Guide: https://github.com/Gissio/ionizing-radiation-field-guide
• The default alarm settings should give you sensible thresholds for general use.
• For dead-time compensation:
  1. Leave the counter running for an extended period — 12 hours or more if possible.
  2. Go to Settings > Statistics and read the dead-time value. The device reports an upper bound on the dead time.
  3. Enter that value as your dead-time compensation.
• For general use, select “None (Cs-137)”. If you're measuring background radiation (i.e. the natural low level of radiation around you), select “Background radiation”.
