Nuclear decay is one of the most extreme processes and is central to a range of fields including energy, medicine, imaging, labelling, archaeology and sensing. Low-energy electrons from radioactivity decay are biologically active. However, it is challenging to generate them locally. In this work, a new radioactive film that enables enhanced low-energy electron emission has been synthesized. Scanning tunnelling microscopy, supported by electronic structure simulations explained the strong stabilty of the film as it underwent radioactive decay. This new radioactive film may have future applications in cancer therapies using nanoparticles.
