ESTIMATED EQUIVALENT RADIATION DOSE AT DIFFERENT ALTITUDES IN EARTH’S ATMOSPHERE
Journal Title: Solar-Terrestrial Physics - Year 2022, Vol 8, Issue 3
Abstract
The paper reports the results of simulation of cosmic ray proton transport through Earth’s atmosphere. The main objective of this work is to obtain characteristics of secondary particle fluxes at different altitudes and to convert them to equivalent dose values. The technique for the conversion is based on numerical simulation of interaction between the particles and an anthropomorphic phantom. The paper examines two cases, using a model source of primary proton spectra as input parameters, which correspond to both purely galactic cosmic rays and solar cosmic rays. The computational results are tabulated for the altitude range from 0 km to 11 km above sea level; the upper range value corresponds to the flight altitude of civilian airliners. These results are shown to agree well with the results obtained by other research teams.

Conditions for the occurrence of intense fluxes of energetic electrons at L<1.2 associated with solar activity and solar wind parameters
We present the results of a statistical study of transient enhancements of electrons with energies >30 keV at low drift shells in the quasi-trapped region (forbidden zone) at the geomagnetic equator. Using data from low-...
POSSIBLE DIFFERENCE IN THE FORMATION OF CORONAL MASS EJECTIONS OF TWO TYPES
Analysis of seven near-limb coronal mass ejections (CMEs) has shown that at distances R<1.4R from the center of the Sun CMEs according to their formation can be divided into two types: type 1 CMEs and type 2 CMEs. In th...
OBSERVATIONS OF SMALL-SCALE ENERGETIC EVENTS IN THE SOLAR TRANSITION REGION: EXPLOSIVE EVENTS, UV BURSTS, AND NETWORK JETS
In this paper, we review observational aspects of three common small-scale energetic events in the solar transition region (TR), namely TR explosive events, ultraviolet bursts and jets. These events are defined in either...
KINEMATIC CHARACTERISTICS OF STEALTH CME IN THREE-DIMENSIONAL SPACE
We have studied and compared kinematic characteristics of the motion of coronal mass ejections (CMEs) in three-dimensional (3D) space for three groups of CMEs for the period 2008–2014. These CME groups include: (i) steal...
