Cyclotron and linac production of Ac-225.
Radium needles that were once implanted into tumours as a cancer treatment are now obsolete and constitute a radioactive waste problem, as their half-life is 1600 years. The reduction of radium by photonuclear transmutation by bombarding Ra-226 with high-energy photons from a medical linear accelerator (linac) has been investigated. A linac dose of 2800 Gy produced about 2.4 MBq (64 microCi) of...
متن کاملSimulation of Experimental Background Using Fluka
In November 1997, Experiment T423 began acquiring data with the intentions of understanding the energy spectra of high-energy neutrons generated in the interaction of electrons with lead. The following describes a series of FLUKA simulations studying (1) particle yields in the absence of all background; (2) the background caused from scattering in the room; (3) the effects of the thick lead shi...
متن کاملEstimation of Neutron Production from Accelerator Head Assembly of 15 MV Medical LINAC using FLUKA Simulations
For the production of a clinical 15 MV photon beam, the design of accelerator head assembly has been optimized using Monte Carlo based FLUKA code. The accelerator head assembly consists of etarget, flattening filter, primary collimator and an adjustable rectangular secondary collimator. Accelerators used for medical radiation therapy generate continuous energy gamma rays called bremsstrahlung r...
متن کاملProduction of Cyclotron
Positron emission tomography in conjunction with radiopharmaceuticals labeled with positron emitting radionuclides opens the possibility of visualizing in vivo in an atraumatic way fundamental parameters of metabolism in man. The main positron emitting radioisotopes carbon-II, oxygen-IS, nitrogen-13 and fluorine-IR used for labeling radiopharmaceuticals (sugars, aminoacids, fatty acids and drug...
متن کاملMuon-induced neutron production and detection with GEANT4 and FLUKA
We report on a comparison study of the Monte Carlo packages GEANT4 and FLUKA for simulating neutron production by muons penetrating deep underground. GEANT4 is found to generate fewer neutrons at muon energies above ∼100 GeV, by at most a factor of 2 in some materials, which we attribute mainly to lower neutron production in hadronic cascades. As a practical case study, the muon-induced neutron...
