Brohogan presents this post explaining the process for building a solar powered wireless radiation monitor:
This project measures the background radiation outside the house, and transmits it to a display station inside the house. The outside sensing unit is solar powered (but it doesn’t have to be), and should have a range of at least 50m. The display station inside the house continuously displays the current background, and logs it to an SD card (along with date / time, temperature and other data). Daily high counts and other information are also displayed.
