title: Tin shielding thicknesses for electrons.
abstract: The transmission of 6, 9, 12, 16, and 20 MeV electrons from a linear accelerator through tin and lead is studied at 0.5 cm depth in polystyrene. These measurements are performed using a 10 x 10 cm2 cone and extend well into bremsstrahlung region. The results show certain advantages of using tin to shield sensitive organs from electron beams. Tin is non-toxic and creates less additional bremsstrahlung even though it must be thicker than the equivalent lead shield.
