Space exploration radiation risks remain a major challenge for long-duration missions. In collaboration with Canadian Nuclear Laboratories, the research team will develop a space radiation protocol simulating heavily shielded environment of Lunar habitats predicted to exhibit high levels of neutron radiation. They propose to use quail (Coturnix coturnix) as a novel non-human research model and to assess the effects of gamma and neutron radiation on skeletal, calcium homeostasis and cardiovascular systems. Similar to humans and rodents, spaceflight experiments with quail eggs showed altered calcium homeostasis and bone loss, demonstrating that quail egg is a valid research model to study fundamental biological questions relevant to spaceflight risks to humans. Moreover, quail meat and eggs have nutritional value and are potentially useful as sustainable food supply for Lunar bases. These studies will pave the way for assessing countermeasures necessary to eliminate the identified risks of the chronic exposure to radiation relevant to Lunar exploration.
