不同钷同位素的生产方法各不相同，本節只给出钷-147的生产方法，因为它是唯一具有工业应用的钷同位素。钷-147是通过用[[热中子]]轰击[[铀-235]]来大量生产的，与其他同位素相比产量相对较高，占铀-235[[裂變產物]]總量的2.6%。{{sfn|Lavrukhina|Pozdnyakov|1966|p=115}}另一种生产钷-147的方法是通过用热中子轰击浓缩的[[钕]]-146或在[[粒子加速器]]中用高能[[质子]]轰击{{le|碳化铀|Uranium carbide}}靶来获得钕-147，接著钕-147快速衰变为钷-147。<ref>{{cite book|title = Applications of inorganic mass spectrometry|year = 2011|page = 144|publisher = Springer|isbn = 978-3-642-21022-8|last1 = Hänninen|first1 = Pekka|last2 = Härmä|first2 = Harri}}</ref>另一种方法是用[[快中子]]轰击铀-238，引起快速裂变，在多种反应产物中产生钷-147。<ref name=De2001>{{cite book|title = Applications of inorganic mass spectrometry|isbn=978-0471345398|year = 2001|author1=De Laeter |author2=J.

在1960年代，[[橡树岭国家实验室]]（ORNL）每年可生产650克钷{{sfn|Lavrukhina|Pozdnyakov|1966|p=116}}，是世界上唯一大批量合成钷的设施，<ref>{{cite book|title = On the Home Front: The Cold War Legacy of the Hanford Nuclear Site|url = https://archive.org/details/onhomefrontcoldw0000gerb_r2s0|year = 2007|edition = 3rd|publisher = University of Nebraska Press|page = [https://archive.org/details/onhomefrontcoldw0000gerb_r2s0/page/162 162]|isbn = 978-0-8032-5995-9|last1 = Gerber|first1 = Michele Stenehjem|last2 = Findlay|first2 = John M.}}</ref>然而[[美国]]在1980年代初已停止了公克级的钷之生产，不過隨著2010年代ORNL的{{le|高通量同位素反應爐|High Flux Isotope Reactor}}的重新啟用，ORNL將有機會恢复钷的生产。{{Update after}}目前，[[俄罗斯]]是唯一较大规模生产钷-147的国家。<ref name="Russia">{{cite book|title = Radioisotope Thin-Film Powered Microsystems|year = 2010|isbn = 978-1441967626|last1 = Duggirala|first1 = Rajesh|last2 = Lal|first2 = Amit|last3 = Radhakrishnan|first3 = Shankar|publisher = Springer|page = 12|url = https://books.google.com/books?id=AoWbhNoLwnYC&pg=PA12|access-date = 2020-06-09|archive-date = 2020-09-26|archive-url = https://web.archive.org/web/20200926111748/https://books.google.com/books?id=AoWbhNoLwnYC&pg=PA12|dead-url = no}}</ref>
