Cross sections for production of the therapeutic radioisotope (131)Cs via the (133)Cs(p,3n)(131)Ba-->(131)Cs route were investigated at cyclotrons. Excitation functions of the (133)Cs(p,x)(133m,133mg,131mg,129g,129m,128)Ba, (132,129cum,127cum)Cs and (129m(ind),127cum,125cum)Xe nuclear reactions were measured up to 70MeV proton energy. The experimental data were compared to the results of model calculations performed by means of ALICE-IPPE, EMPIRE-II and TALYS computer codes. Good overall agreement was observed. On the basis of the measured excitation functions integral yields were deduced. Charged particle production routes of (131)Cs are discussed.
