This project provides two different things: a new design of manufacture-friendly ion chamber, and also a proof-of-concept device that demonstrates its sensitivity to radiation.

From the start, the idea has been to create a hand-held detector that can be used to check if an object is radioactive or not.

The sketch on the left was made at the start of the project. Next to it you can see the latest design :-)

As mentioned in the previous log entry, the ion chamber design has been modified to have a positive electrode that is smaller and placed in central position.

Next entries will show more details on the schematic.
