Inotropic myocardial function dynamics in patients with recurrent atrial fibrillation
Aim. To study inotropic myocardial function of left and right ventriculum (LV, RV) in patients with recurrent atrial fibrillation (AF), according to balanced radionuclide ventriculography (BRVG) data. Material and methods. The study included 72 patients:

Numerical simulation of a temporary repository of radioactive material [PDF]
The use of computer simulations techniques is an advantageous tool in order to evaluate and select the most appropriated site for radionuclides confinement. Modelling different scenarios allow to take decisions about which is the most safety place for the final repository.

Eighteen patients with a history of previous anterior myocardial infarction and suspected left ventricular aneurysms were studied both by contrast left ventriculography and by first pass radionuclide ventriculography using Technetium99m and a ...

The origin of $^{60}$Fe and other short-lived radionuclides in the early solar system [PDF]
Establishing the origin of short-lived radionuclides (SLRs) with half-lives $\leq$ 100 Myr has important implications for the astrophysical context of our Sun's birth place. We review here the different origins proposed for the variety of SLRs present in the solar accretion disk 4.57 Ga ago.

Measurements of proton-induced radionuclide production cross sections to evaluate cosmic-ray activation of tellurium [PDF]
We have measured a large number of proton-induced radionuclide production cross sections from tellurium targets of natural isotopic composition at incident energies of 0.80, 1.4, and 23 GeV. The results of these measurements are compared to semi-empirical calculations.

Simulation of induced radioactivity for Heavy Ion Medical Machine [PDF]
For radiation protection and environmental impact assessment purpose, the radioactivity induced by carbon ion of Heavy Ion Medical Machine (HIMM) was studied. Radionuclides in accelerator component, cooling water and air at target area which are induced from primary beam and secondary particles are simulated by FLUKA Monte Carlo code.
