Using two detectors concurrently to monitor ambient dose equivalent rates in vehicle surveys of radiocesium contaminated land [PDF]

Journal of Environmental Radioactivity, 2017
In response to the accident at Tokyo Electric Power Company's Fukushima Dai-ichi Nuclear Power Plant (FDNPP), vehicle-borne monitoring was used to map radiation levels for radiological protection of the public. By convention measurements from vehicle-borne surveys are converted to the ambient dose equivalent rate at 1 m height in the absence of the ...

The neutron dose equivalent around high energy medical electron linear accelerators [PDF]

Nuclear Technology and Radiation Protection, 2014
The measurement of neutron dose equivalent was made in four dual energy linear accelerator rooms. Two of the rooms were reconstructed after decommissioning of 60Co units, so the main limitation was the space. The measurements were performed by a

Dose calculations in aircrafts after Fukushima nuclear power plant accident – Preliminary study for aviation operations [PDF]

, 2019
There is little information to decision support in air traffic management in case of nuclear releases into the atmosphere. In this paper, the dose estimation due to both, external exposure (i.e. cloud immersion, deposition inside and outside the aircraft)

Radiation Dosimetry Estimations in the Venusian Atmosphere during Different Periods of Solar Activity

Universe, 2022
The new space era has expanded the exploration of other planets of our solar system. In this work, radiation quantities are estimated in the Venusian atmosphere using the software tool DYASTIMA/DYASTIMA-R, such as the energy deposit and the ambient dose ...
