Abstract (en)
[origin: WO0022628A1] The invention relates to highly radioactive miniaturized cylindrical radiation sources made of strontium 90/titanate, strontium 90/ zirconate and strontium 90/silicate. Said radiation sources have an activity that is greater than 25 mCi/mm<3>, preferably >/= 30 mCi/mm<3>, and a diameter of less than 0.7 mm, preferably less than 0.4 mm. The invention also relates to a method for producing these extremely small but highly radioactive radiation sources.
