Radiation in Space with Dr. Ron Turner

Radiation in Space with Dr. Ron Turner

As we move into a new era where activities in space become more routine (space hotels, moon bases, colonization of Mars, the proposed Space Force) the presence of radiation in space will have to be contended with. In this inaugural episode of VersantCast, our guest is Dr. Ron Turner, an internationally recognized expert in radiation risk management for astronauts, with over thirty years experience in space systems analysis from requirements definition to system architecture evaluation. In our discussion, we covered topics such as the radiation risks and exposure for commercial tourists in space, the realities of radiation threats and their long term impacts on astronauts, and the likelihood of turning into the Hulk during a solar storm. ...
