Abstract
A thin window counter with special mica‐to‐glass seal has been developed especially for the detection of low energy electrons from radioactive isotopes such as C14. It is simple to construct and has proved to be vacuum tight. It can be operated without external quenching and exhibits flat plateaus of 100 to 300 volts. The average useful life of these counters is around a year or more. The efficiency of the counters is very satisfactory.Keywords
