Life Sci Space Res (Amst)
. 2023 Apr;
37:39-49.
PMID: 37087178
Background: The limitations to prolonged spaceflight include unloading-induced atrophy of the musculoskeletal system which may be enhanced by exposure to the space radiation environment. Previous results have concluded that partial...

NPJ Microgravity
. 2019 Jun;
5:13.
PMID: 31231675
Astronauts traveling beyond low Earth orbit will be exposed to galactic cosmic radiation (GCR); understanding how high energy ionizing radiation modifies the bone response to mechanical unloading is important to...

Radiat Res
. 2017 Aug;
188(4):433-442.
PMID: 28771086
Exposure to high-dose ionizing radiation during medical treatment exerts well-documented deleterious effects on bone health, reducing bone density and contributing to bone growth retardation in young patients and spontaneous fracture...

Braby L
Health Phys
. 2016 Jan;
110(3):252-5.
PMID: 26808875
It seems likely that the biological consequences of radiation exposure are the result of sequences of biochemical processes initiated by the chemical changes caused by energy deposited as ionization or...

Health Phys
. 2015 Aug;
109(4):284-95.
PMID: 26313586
Uncertainties persist regarding the assessment of the carcinogenic risk associated with galactic cosmic ray (GCR) exposure during a mission to Mars. The GCR spectrum peaks in the range of 300(-1)...

Health Phys
. 2015 Apr;
108(6):574-9.
PMID: 25905518
Coincident counts can be observed in experimental radiation spectroscopy. Accurate quantification of the radiation source requires the detection efficiency of the spectrometer, which is often experimentally determined. However, Monte Carlo...
