Conceptual Design Study of 13 MeV Proton Cyclotron [PDF]

, 2012
A study to determine the conceptual design of a 13 MeV proton cyclotron for PET (Positron Emission Tomography) facility has been carried out. Based on studies on reactions of PET radioisotopes production, reaction cross-sections and some design ...

Investigation of the Physical Properties of Different Ion Species at Hadron Therapy; A Comprehensive Study

Frontiers in Biomedical Technologies
Purpose: Recently, using hadrons as a therapeutic beam has been highly advised for radiation treatment of mainly deep-seated tumors due to the desired conforming of three-dimensional dose conformation onto tumor volume.

$^{39}$Ar dating with small samples resolves ocean ventilation [PDF]

arXiv, 2018
Ocean ventilation is the integrated effect of various processes that propagate surface properties to the ocean interior. Its precise understanding is the prerequisite for addressing essential questions such as oxygen supply, the storage of anthropogenic carbon and the heat budget of the ocean.

155Tb production by cyclotrons: what level of 155Gd enrichment allows clinical applications? [PDF]

arXiv, 2023
BACKGROUND: 155Tb represents a potentially useful radionuclide for diagnostic medical applications, but its production remains a challenging problem. A recent experimental campaign, conducted with low-energy proton beams impinging on a 155Gd target with 91.9% enrichment, demonstrated a significant co-production of 156gTb, a contaminant of great concern

Review of Past Nuclear Accidents: Source Terms and Recorded Gamma-Ray Spectra [PDF]

, 1997
Airborne gamma ray spectrometry using high volume scintillation detectors, optionally in conjunction with Ge detectors, has potential for making rapid environmental measurements in response to nuclear accidents.

Recovery of radioisotopes from nuclear waste for radio-scintillator-luminescence energy applications [PDF]

arXiv, 2012
Extraction of the light weight radioisotopes (LWR) 89Sr/90Sr, from the expended nuclear bars in the Fukushima reactor, should have decreased the extent of contamination during the course of the accident. 89Sr applications could pay for the extraction of 89Sr/90Sr from nuclear residues.

Measurement of radon concentrations at Super-Kamiokande

, 1999
Radioactivity from radon is a major background for observing solar neutrinos at Super-Kamiokande. In this paper, we describe the measurement of radon concentrations at Super-Kamiokande, the method of radon reduction, and the radon monitoring system.

Peaceful atoms in agriculture and food : how the politics of the Cold War shaped agricultural research using isotopes and radiation in post war divided Germany [PDF]

, 2015
During the Cold War, the super powers advanced nuclear literacy and access to nuclear resources and technology to a first-class power factor. Both national governments and international organizations developed nuclear programs in a variety of areas and ...

Future Supply of Medical Radioisotopes for the UK Report 2014 [PDF]

arXiv, 2015
The UK has no research nuclear reactors and relies on the importation of 99Mo and other medical radioisotopes (e.g. Iodine-131) from overseas (excluding PET radioisotopes). The UK is therefore vulnerable not only to global shortages, but to problems with shipping and importation of the products.
