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.
