You could have your task create a text file and have a service that binds to a REC event, reads the text file and adds the radiation to the archive record. Weewx would then take care of the daily stats in archive_day_radiation for you. Alternatively your service could still bind to the REC, but instead of reading the text file it could retrieve via the API the current radiation value and thus do away with the cron task altogether.
