The capability of Anomalous Long Term Effects in Astronauts (ALTEA) to measure the linear energy transfer (LET) of protons and helium and the kinetic energy of protons and heavy ions is to be upgraded by the addition of a new time of flight (TOF) system detector called the Light Ions Detector for ALTEA (LIDAL). LIDAL upgrades the ability of ALTEA to make measurements that can be converted, by dedicated software in real-time, into radiation risk coefficients - effectively enabling ALTEA to become the first ever dosimetric “risk meter” aboard the International Space Station.
