Aircraft crew are one of the groups of radiation workers which receive the highest annual
exposure to ionizing radiation. Validation of computer codes used routinely for calculation of …

The release of radioactive plumes can occur due to nuclear power plant accidents, terrorist
attacks, or scenarios in the chemical, biological, radiological, and nuclear defense (CBRN) …

Background Cosmic ray-induced particles can lead to failure of semiconductors packaged
for export during air transport. This work performed MCNP 6.2 simulations to optimize …

During the flight, an aircraft is submitted to a radiation environment composed of cosmic-ray-
induced particles (CRIP) of which neutrons are responsible for approximately 40% of the …

Several applications exist that calculate cosmic-ray-induced particle (CRIP) spectra as a
function of the altitude in the atmosphere. In general, the Earth's magnetic field is only used …

Cosmic-ray-induced particles at flight altitude present an increasing concern because of the
development of aircraft with high maximum cruising altitude (higher than 40 000 ft) and …

The radiation shielding characteristic of neutron shielding material has been studied as the
preliminary study in order to design cosmic-ray shielding material. Specially, Soft Magnetic …

Cosmic radiation, highly energetic particles from outer space, interacts with the atmosphere
and cause a cascade of secondary cosmic radiation-inducedparticles [1, 2]. At the flight …

A TLD-based dosimeter of polyethylene–lead–polyethylene, was developed and
characterized with Monte Carlo simulations, using the MCNPX code. This passive system for …
