Measuring radiation at the International Space Station

Editor’s Highlight—

 

This paper offers some very practical insight into how radiation and radiation dose is measured at the International Space Station (ISS). The authors provide simultaneous, long-term estimates of radiation dose external to the ISS for four source categories: (i) galactic cosmic ray particles and their secondary products; (ii) protons in the South Atlantic Anomaly region of the inner radiation belt; (iii) relativistic electrons and/or bremsstrahlung in the outer radiation belt; and (iv) solar energetic particle events and explain how these are categorized. The authors also reference the relevant literature to provide the reader with a history of how the measurement system external to the ISS has developed.  Figure 3 in the manuscript, which provides McIlwain L-shell profiles of the dose rates measured with the R3DR2 instrument for the period 11-20 and 21-30 June 2015, is particularly instructive.
