An improved radium safe.

For many years it has been the usual practice to store radium in a standard money safe. When the radium is required for clinical work, this is unlocked and the radium is carried to the loading area where it is sterilised and prepared for use. This procedure involves an unnecessary exposure to personnel and for this reason a radium safe has been designed in which the radium is stored immediately below the working surface. Five of these radium safes have been made and are installed in various clinics of the Ontario Cancer Research and Treatment Foundation. The oldest has been in use for the past ten years. All have proved to be very reliable and satisfactory.
