Monte Carlo-based revised values of dose rate constants at discrete photon energies

Journal of Medical Physics, 2014
Absorbed dose rate to water at 0.2 cm and 1 cm due to a point isotropic photon source as a function of photon energy is calculated using the EDKnrc user-code of the EGSnrc Monte Carlo system.

Radon concentration and radiation hazard of a rare earth waste dump in China

Kuwait Journal of Science, 2023
The 222Rn activity concentration and air absorbed dose rate of a rare earth waste slag heap in China were measured by radon and air absorbed dose rate instruments. A total of 34 monitoring points including waste residue heaps were selected.

Monitoring of the absorbed dose of rates radiation in the rural areas [PDF]

The University Thought - Publication in Natural Sciences, 2016
Man is constantly exposed to radiation from the radionuclides from the environment. This study presents the results of measuring the absorbed dose rates of natural ionizing radiation in rural areas in the municipality of Štrpce, in southern part of Kosovo and Metohija.

Activity of natural radionuclides and their contribution to the absorbed dose in the fish cubera snapper (lutjanus cyanopterus, cuvier, 1828) on the coast of Ceara, Brazil

Brazilian Journal of Oceanography, 2010
A methodology was developed for converting the activity concentration of radionuclides (Bq kg-1) into absorbed dose rate (Gy y-1), aiming an approach to environmental radioprotection based on the concept of standard dose limit.

Active Dosimetry with the Ability to Distinguish Pulsed and Non-Pulsed Dose Rate Contributions [PDF]

EPJ Web of Conferences, 2021
This paper presents the concept of an active dosimetry system and its operational regime for pulsed radiation dose rate measurements. The plastic scintillator is suggested to be used for absorbed dose rate measurements.

Galactic Cosmic Ray induced absorbed dose rate in deep space – Accounting for detector size, shape, material, as well as for the solar modulation

Journal of Space Weather and Space Climate, 2019
Depending on the radiation field, the absorbed dose rate can depend significantly upon the size of the detectors or the phantom used in the models. In deep space (interplanetary medium) the radiation field is on avarage dominated by Galactic Cosmic Ray ...
