Frequently Ask Question

• Why uses paper for the negative pole(cathode)?
  Paper is a high resistance film (G ohms), and makes electric charge disappearance quiet. It is immeasurable if a detection pulse is too short.
• Is the electrical connection of paper and the lead carried out with a bond?
  In the high voltage, paper carries out behavior near a conductor. An electric charge moves to the lead from paper.
• It sounds beep from a transformer.
  Transformer voltage step-up is oscillated by outside. The oscillation vibrates the transformer slightly and becomes the sound.
• Even if turning off, it sounds small PUCHIPUCHI from an air Geiger Mueller counter.
  This is the electric discharge sound by radiation detection. Since operation voltage does not immediately fall even if turning off.
• How much Butane gas should be put in?
  It seems that there is optimal density.
• It seems that geiger counter will count, turning to the sun.
  It seems that the ultraviolet rays from the sun have influenced measurement. Try to paint the window with black magic, to omit ultraviolet rays.
