⁹⁹Mo Production via¹⁰⁰Mo(n,2n)⁹⁹Mo using accelerator neutrons

Abstract

Abstract.A new production method of 99 Mo using accelerator neutrons via the 100 Mo(n,2n) Tc was obtained by employing a sublimation method. Accelerator neutrons are shown to have a great potential to produce a wide variety of radioisotopes.

Development of ⁹⁹Mo/^99mTc Generator System for Production of Medical Radionuclide ^99mTc using a Neutron-activated ⁹⁹Mo and Zirconium Based Material (ZBM) as its Adsorbent

“…Production of 99m Tc using electron LINAC is reported to be technically simple and economically and ecologically feasible [10]. Similar research also reveals that 99 Mo can be produced via nuclear reaction of 100 Mo(n,2n) 99 Mo using neutrons with energy of 14 MeV resulting from bombarding Be or C with 40 MeV deuteron beam [11]. Other researchers report concerning evaluation of experimental data for production of 99 Tc is higher in cyclotron product.…”

New developments in the experimental data for charged particle production of medical radioisotopes

“…-Production cross section of 90,95g Nb and 88 Y with side products by proton irradiation of natural zirconium [54] (PET). -Production cross section of 11 C, 15 O and 13 N isotopes by proton irradiation of the corresponding target elements [55] (PET). -Production of 67 Cu by deuteron irradiation of natural zinc [56] (therapy).…”

“…Several attempts have been made to elaborate methods to substitute the reactor HEU (highly enriched uranium) production route by LEU (low enriched uranium target), fast neutron [15,16], high energy photon [17] and charged particle irradiation, both for 99 Mo production [18,19] and direct 99m Tc production [20].

“…2.1 Production of 99 Mo/ 99m Tc generator Shutdown and decommissioning of several nuclear reactors responsible for the large-scale production of 99 Mo caused (or will cause in the near future) a shortage on the market of the 99 Mo/ 99m Tc generator system. Several attempts have been made to elaborate methods to substitute the reactor HEU (highly enriched uranium) production route by LEU (low enriched uranium target), fast neutron [15,16], high energy photon [17] and charged particle irradiation, both for 99 Mo production [18,19] and direct 99m Tc production [20].

Measured bremsstrahlung photonuclear production of 99Mo (99mTc) with 34 MeV to 1.7 GeV electrons

“…Numerous approaches have been explored for alternate means of 99m Tc production, either directly or as the daughter decay product of 99 Mo (Bernard 2014, TRIUMF report 2008, Wolterbeek 2014, Culter 2014, IAEA report 2013, Nagai 2014, Pillai 2012, Guerin 2010. Some promising methods are being adopted by commercial companies, including the use of low enrichment uranium (LEU), e.g.…”
