How this is generated

This entropy is taken from a geiger counter. The radiation events detected are converted to bytes, which are stored in a database. This radiation-based data is then hashed in 64-byte chunks with SHA256 to generate 32-byte chunks, starting with the most recently received 64 bytes. The first block is generated from just the radiation data; subsequent blocks are generated from both the preceding 32-byte output chunk and the next 64 bytes of radiation data.
