Recent progress in space weather research for cosmic radiation dosimetry

Sato, Tatsuhiko   

The radiation environment in space is a complex mixture of particles of solar and galactic origin with a broad range of energies. For astronaut dose estimation, three sources must be considered, namely, galactic cosmic rays (GCR), trapped particles (TP), and solar energetic particles (SEP). More details about the radiation environment in space will be discussed at the symposium, together with the recent progresses on the space weather research for nowcasting and forecasting the astronaut doses due to SEP exposure.
