Nuclear Fragmentation in Therapeutic and Diagnostic Studies with Heavy Ions

Radiation Chemistry of High-Energy Carbon, Neon, and Argon Ions: Integral Yields from Ferrous Sulfate Solutions

“…expect the spectrum of fragment sizes to shift towards heavier fragments (and away from light ones) as the atomic number of the projectile increases. Chatterjee et al23 have calculated from cosmic ray data the fragmentation probabilities in water for incident nitrogen and oxygen nuclei. It is clear that heavier fragments are more important with the heavier (oxygen) ion.…”

A porous hexagonal boron nitride powder compact for the production and release of radioactive 11C

“…The measurements were carried out in high precision mode (0.05 torr pressure tolerance and 180 s equilibration time [49]). To ensure higher precision, P 0 was 1 The median of a particle size distribution is defined as the size where 50% of the particles present a larger and smaller diameter. measured simultaneously in the second cell, for every third measurement point.…”

“…The advantage of using PET-isotopes such as 11 C for external beam radiation therapy has been subject of many discussions and studies. Pioneer work was performed at the Bevalac at the Lawrence Berkeley Laboratory, where the utilization of Radioactive Ion Beams (RIBs) for hadron therapy was originally proposed and examined [1][2][3]. The exploitation of 11 C as a therapeutic beam has re-gained increased attention after pilot-studies at NIRS, Chiba, where low-intensity 11 C beams have been produced by projectile fragmentation for pre-clinical imaging studies [4,5].…”

On‐line characterization of heavy‐ion beams with semiconductor detectors

“…Although we obtain reliable informationr:outinely about the dose delivered to a subject under all the irradiation conditions encountered, there is no experimental detailed knowledge of which particles generate the delivered dose and the contribution by each type of fragment. Chatterjee et al 2 have described the general characteristics of the complex beams that can be used for biomedical applications based on information obtained frof(1 cosmic-ray data.…”
