Some factors that bind the bones have long been known. Among other things, astronauts are humiliated by low gravity, and patients with cancer who receive radiation therapy have a greater bone fracture. But it has never been studied why bones flex due to radiation. Biology engineers at Clemson University discover in South Carolina that low-intensity ionizing radiation can destroy the essence of bones.

In the laboratory experiment, four mouse groups suffered different intensity radiation. The first group suffered gamma-ray radiation, similar to that suffered during a radiation therapy session. The second suffered radiation from protons, similar to that suffered by an astronaut on a Moon walk. The third group suffered iron radiation and the fourth was carbon radiation, similar to those an astronaut would suffer on a trip to Mars.

After 110 days the mice were killed and their skeleton was studied using three-dimensional images. It was found that a quarter of the mouse pulp was destroyed and that half of the internal structure of the bones to support weight was damaged.
