“…These measured spectra, and example spectra of 227 Ac, 227 Th, 223 Fr, and 223 Ra (with its daughters) are displayed in Figure 3A–3F, where example spectra were generated calculated using GADRAS (Mitchell, 1992) and previously determined detector response models. In these Figures the live-time corrected background has been subtracted from the measurement.…”

The alpha particle emitter Radium-223 dichloride (223RaCl2) has recently been approved for treatment of late-stage bone metastatic prostate cancer. There is considerable interest in studying this new agent outside of the clinical setting, however the supply of 223Ra is limited and expensive. We have engineered a 223Ra microgenerator using traces of 227Ac previously generated from cyclotron-produced 225Ac. Radiochemically pure 223RaCl2 was made, characterized, evaluated in vivo, and the source was recovered in high yield for regeneration of the microgenerator.

The Gamma Detector Response and Analysis Software-Detector Response Function (GADRAS-DRF) application computes the response of gamma-ray and neutron detectors to incoming radiation. This manual provides step-by-step procedures to acquaint new users with the use of the application. The capabilities include characterization of detector response parameters, plotting and viewing measured and computed spectra, analyzing spectra to identify isotopes, and estimating source energy distributions from measured spectra. GADRAS-DRF can compute and provide detector responses quickly and accurately, giving users the ability to obtain usable results in a timely manner (a matter of seconds or minutes).

“…High fidelity simulations of detector response to mixed neutron and gamma radiation fields has important applications in the optimization and design of measurement systems and the interpretation of observed spectra [1]. The conversion of a flux incident on an active detector volume into a realistic energy spectrum is facilitated by Detector Response Functions (DRFs).…”

a b s t r a c tThis work presents the organic scintillation simulation capabilities of DRiFT, a post-processing Detector Response Function Toolkit for ® MCNP output. DRiFT is used to create realistic scintillation detector response functions to incident neutron and gamma mixed-field radiation. As a post-processing tool, DRiFT leverages the extensively validated radiation transport capabilities of ® MCNP 6, which also provides the ability to simulate complex sources and geometries. DRiFT is designed to be flexible, it allows the user to specify scintillator material, PMT type, applied PMT voltage, and quenching data used in simulations. The toolkit's capabilities, which include the generation of pulse shape discrimination plots and full-energy detector spectra, are demonstrated in a comparison of measured and simulated neutron contributions from 252 Cf and PuBe, and photon spectra from 22 Na and 228 Th sources. DRiFT reproduced energy resolution effects observed in EJ-301 measurements through the inclusion of scintillation yield variances, photon transport noise, and PMT photocathode and multiplication noise.Published by Elsevier B.V.
