During the operational life of a PET cyclotron, the concrete walls of the vault are activated by
secondary neutrons. For the dismantling of such accelerator facilities, a considerable …

Medical linear accelerators are increasingly used in radiotherapy. During the operational life
of the accelerator, the different components of the LINAC head become radioactive due to …

A portable neutron spectrometry system was designed based on thermal neutron detectors
embedded in concentric polyethylene spherical shells. The system is flexible and can …

Low-energy medical cyclotrons with energy below 20 MeV are widely used to produce short-
lived radionuclides for Positron Emission Tomography (PET). One of the main reactions in …

This work evaluated the validity of computer simulation codes by comparing the results of an
inventory calculation for a 89 Zr target assembly with measured data obtained using a high …

This work investigated the most suitable type of degrader (Cu, Al or Nb) and its thickness,
taking into consideration the salient aspects of concrete activation for high-purity 89 Zr …

Abstract 18 F is an important radioisotope used in nuclear medicine for diagnostic purposes.
It is produced most often via 18 O (p, n) 18 F reaction. During its production, the oxygen …

Despite the many emerging applications of neutron radiation in the Philippines, there is a
gap in the country's capability to calibrate neutron radiation monitoring instruments that are …

Neutron activated concrete reference material for measurement of residual radioactivity by
gamma-ray spectrometry has been prepared. The main radionuclides were 60Co, 152Eu …

In the widespread use of medical cyclotrons for isotope production, radiological and
economic consequences related to the decommissioning of particle accelerators are often …
