title: Sensitivity in electron microscope autoradiography for calcium-45.
abstract: The sensitivity of Ilford L4 emulsion to 45Ca was determined for electron microscope autoradiographic conditions. Sensitivity values were obtained for monolayers and double layers of emulsion in combination with various developing procedures. The dependence of sensitivity upon radiation dose was determined. All results are compared to previously calibrated isotopes.
