I bought one CI-22BG tube and one CI-3BG tube for total of 16G. Because I didn`t have anything radioactive to test my Geiger counter, I also ordered a piece of radioactive Fiesta dinnerware from ebay. Red Fiestware used to have uranium oxide in its glaze....

It uses the simpler method of direct frequency measurement which is easy to do but means that the number of digits displayed depends on the input frequency. If you want to display all digits all the time there is a technique called reciprocal counting- but....
