Watch the Q&A: • Q&A: The Radioactivity...
Frances Staples is a PhD student at UCL studying the dynamics of the Van Allen radiation belts - rings if relativistic particles trapped in Earth’s magnetic field. During her Master's in physics at Lancaster University she specialised in space science, researching convection in the Earth’s ionosphere. Her research interests focus on improving our understanding of the complex interactions between the solar wind and Earth’s magnetosphere. Better knowledge of this system will aid space weather forecasting models, allowing action to be taken to mitigate damage to technology and infrastructure.
This talk and Q&A was filmed in the Ri on 20 July 2019.

Fantastic lecture; she could have gone on for 2 hours and I would have been completely fine with it. This is one of my favorite topics in science.

This and artificial gravity. Detriments of radiation maybe a bit more long term, but little to no gravity drastically effects the body in quite short order. Both are primary problems that must be solved.

Solar plasma is accelerated owing to the nonuniformity of the solar magnetic fields in the solar spots. These solar spots containing helium are colder and have higher magnetic fields than the solar magnetic field. The intensity and the number of these solar spots increases during solar maxima so do their magnetic fields that accelerate the solar particles up to 10,000 km/sec.

Yup, I'm gonna need a Jedi mind trick now for anyone who's read this. :-D That still leaves one problem though: their chart then contains local items and suddenly jumps to the non-sequitur of volcanoes occurring elsewhere (unless they mean that all of the other problems are considered to occur elsewhere as well, and the impacts indirectly cascade).

kristian birkeland was egnored and is still not fully recognized nor understood. "magnetic flux ropes" are electric currents along a magnetic field and are named birkeland currents. it is very hard for an astrophysicist to say the word electric. they will talk of "winds in the vaccum of space"... It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. Kristian Birkeland

They had far less understanding of radiation in space back in the 40's. In fact, it wasn't until they started launching satellites in the late 50's that they had any idea of how much radiation (and what kinds) were out there.
