Oral

With obtaining radioactive isotope (RI) beam with a wide range of mass number, the utilization of high-intensity uranium-238 beam is adopted or planned, such as Facility for Rare Isotope Beams.
As one of the such facilities, Radioactive Isotope Beam Factory (RIBF) at RIKEN provides uranium-238 beam, the energy of which is 345 MeV/u. The current intensity of the uranium-238 beam is 70 pnA....

Oral

A photonuclear reaction consists of the photoabsorption and particle emission. Once the photon is absorbed, the excited nucleus decays via direct, preequilibrium and compound (evaporation) mechanisms. Photoneutron production yields and production mechanisms were investigated by comparing results of the well-known estimation methods. Differential photoneutron yields from 𝑛𝑎𝑡Pb,197Au, 𝑛𝑎𝑡Sn and...

57. Impact of new delivery methods in proton therapy on radiation protection of Compact Proton Therapy Centers (CPTC)

2. Shielding and dosimetry

Oral

In their eagerness to improve clinical results, the delivery methods in proton therapy are moving towards more precise techniques with the goal of increasing their therapeutic index. Once the primal passive scattering methods were overcome by current active scanning process, the evolution continues and news delivery methods such as arc therapy, minibeams or flash therapy, among others, are...
