The New Fabrication Method of a Surface Source


A standard surface source is a planar radioactive source material. It is used as a surface source for the calibration of hand-foot cloth monitors and survey meters. We have developed a new method for the fabrication of standard surface sources. Uniform printing density, a broad range of radioactive intensity, high positional resolution and arbitrary shapes could be also realized by the method. The printed sources will be applied for a radioactive logarithmic scale for imaging plate and a radioactive surface source for calibration of radiation measurement instruments.

A broad range of radioactive concentrations can be obtained by setting inks, with different radioactive concentrations, in an inkjet printer and using the adjustment function of printing concentrations for each ink color.
