Quantitative assessment of Tm isotope production: experimental data analysis and model validation.

Tm is an effective radioisotope for use in theragnostic purposes. This study aims to find the best alternative routes for producing Tm for appropriate cancer therapy and diagnostics. In this study, we comprehensively analyzed production cross-sections of Tm and investigated the behavior of these reactions using six different level density models and refined optical model potential (OMP) parameters with the nuclear reaction code TALYS 1.

Monte Carlo calculations of target fragments from helium and carbon ion interactions with water.

When high energetic heavy ions interact with any target, short range, high linear energy transfer (LET) target fragments are produced. These target fragments (TFs) can give a significant dose to the healthy tissue during heavy ion cancer therapy, and when cosmic radiation interacts with astronauts. This paper presents Monte Carlo simulations, using the Particle and Heavy Ion Transport code System (PHITS), to characterize target fragments from reactions of helium and carbon ions with water.

Assessment of radionuclides in the soil of residential areas of the Chittagong metropolitan city, Bangladesh and evaluation of associated radiological risk.

Soil samples from the three residential hubs of Chittagong city, Bangladesh were analyzed using gamma spectrometry to estimate radiation hazard due to natural radioactive sources and anthropogenic nuclide (137)Cs. The activity concentration of (226)Ra was found to be in the range 11-25 Bq.kg(-1), (232)Th in the range 38-59 Bq.
