A preliminary note on the radioactivity of wrist watches with luminous dials
Keywords: Radioactivity, Wrist watch, Luminous dials
AbstractThe activities of 25 wrist watches with luminous dials were experimentally measured. The mean gamma activity was 0.075 microcurie radium equivalent. Under certain simplifying assumptions the radiation dose to the gonads was calculated. The dose is not likely to exceed about 5 milliroentgens per year in the majority of cases.
