STUDY DESCRIPTION
The data have been generated in the framework of a CONCERT research project "PODIUM". The project objective is to develop an online application in which occupational doses are calculated individually, instead of measuring them with one or more dosemeters. For that purpose, the spatio-temporal radiation field, including its energy and angular distribution, needs to be known. Input is used from fixed dose monitors, and real movements of exposed workers are captured and transferred to the calculation application.
Because of the limited time frame, an intermediate approach with pre-
calculated fluence to dose conversion coefficients for phantoms of different statures and postures has been used simultaneously.
These conversion coefficients are stored here.

DATASET NAME
Neutron fluence to dose conversion coefficients
DOIDOI:10.20348/STOREDB/1156/1219
DATASET DESCRIPTION
For neutrons, broad parallel beams incident on the whole body were considered. The angles of incidence are horizontal and 45° upwards, along the vertical axis and along the horizontal axis, from 0° to 315°, in steps of 45°.

DATASET NAME
Photon fluence to dose conversion coefficients
DOIDOI:10.20348/STOREDB/1156/1218
DATASET DESCRIPTION
The photon conversion coefficients are relevant to interventional radiology. Hence, phantoms with protective lead garment were used for the simulations, and radiation incidence is limited to (a) the upper part of the body and (b) anterior and anteriorly oblique directions of photon incidence. To account for the inhomogeneous radiation incidence on the body, the body was sub-divided into six smaller sections (called “panels”) for which separate conversion coefficients were calculated. There were three panels in height (called “Top”, “Mid”, and “Bottom”), on both sides (left and right). On each of these panels, incidence of parallel mono-energetic photon beams under various angles was considered. Angles in horizontal directions ranged from 60° left-anteriorly oblique (“LAO60”) to 60° right-anteriorly oblique (“RAO60”), in steps of 15 degrees. Anterior radiation incidence is corresponding to 0°. The angles in vertical directions ranged from 30° upward (“Up30”) to 30° downward (“Do30”), also in steps of 15°, where horizontal incidence is corresponding to 90°. All combinations of horizontally and vertically oblique angles were considered. The photon energies were ranging from 10 keV to 120 keV in steps of 10 keV.
