Handmade Air Geiger Counter
Measurement of space radiant rays
Let's measure the difference in the dose of radiation by altitude.
You had better do on the plane. I measured it on the alpine road shown altitude.
It is the Fuji Subaru line of Yamanashi Prefecture.
Measurement result
where | Altitude[m] | Average[cpm] |
The second stage | 1596 | 455 |
Osawa parking | 2020 | 1027 |
The fifth stage | 2305 | 3270 |
Amazing!
The atmospheric pressure inside the air GM tube falls as altitude goes up. And then probably, detection efficiency increased.
