“…Various techniques for preparing radioactive sources have been reviewed [3,7], among which electrodeposition, in which a radioactive material dissolved in an electrolyte solution is electrodeposited on a cathode (source support) by passing an electric current, is commonly used to prepare ultrathin solid radioactive sources [9][10][11][12][13][14][15][16][17]. The advantages of this source preparation method include high deposition yields (99.8%) and high qualities of the sources obtained with simple and inexpensive equipment [7], which make it the most common method of radioactive source preparation.…”
