Cosmic-Radiation Dosimetry Using Electronic Personal Dosemeter (EPD) at Commercial Aircraft Altitude

Active electronic personal dosemeter in interventional radiology.

A recently developed active electronic personal dosemeter (AEPD) was utilised in order to measure the levels and the structure of occupational exposure to scattered X-ray radiation of medical staff who performed percutaneous revascularisation therapy that involves interventional radiology (IR) on the pelvis and upper leg arteries. The AEPDs, placed on the operators' and assistants' chests, that...

High Altitude Cosmic Ray Radiation Detection

Earth’s atmosphere is constantly being bombarded with cosmic rays. However, the origin and effect of this radiation is relatively unknown. We report on the results of a payload that was launched on the balloon sat EOSS flight 201 under the fall DemoSAT program for the COSGC. The payload was designed to measure these cosmic rays using an onboard geiger counter. These results are intended to be u...

The Development of a Personal Dosemeter for Use by Aircraft Crew

This paper describes preliminary work to develop a cosmic-radiation dosemeter for use by military aircraft crew. The dosemeter is based on a combination of CR-39 etched-track detectors and TLD-700 thermoluminescent detectors. It is intended that the CR-39 be used to assess the neutron dose, while the TLD700 is used to assess the photon and charged particle dose. The sensitivity of CR-39 to the ...

COSMIC RADIATION IN COMMERCIAL AVIATION Professor

This paper reviews the current knowledge of cosmic radiation and its applicability to commercial aviation. Galactic cosmic radiation emanates from outside the solar system, while occasionally a disturbance in the sun’s atmosphere leads to a surge in radiation particles. Protection is provided by the sun’s magnetic field, the earth’s magnetic field, and the earth’s atmosphere. Dose rates are dep...
