Our site and the GGreg20_V3 DIY Geiger counter product are referenced by the author of the book Francesco Riggi, published by Springer in April 2024 under the title Educational and Amateur Geiger Counter Experiments.
The book is devoted to theoretical foundations and practical experiments with Geiger counters. In particular, the book deals with DIY counters, which are developed by radio amateurs and are quite popular components for various IoT projects.
Thank you for mentioning our projects and company in the book. We are glad to be a part of the community of DIY enthusiasts who managed to release their own product, which has found its users in more than 20 countries around the world.
