Radiation on the surface of the Moon from GCR particles during minimum solar activity is about 1.4 mSv/day.
Radiation on the surface of the Moon from GCR particles during maximum solar activity is about 0.6 mSv/day.
Radiation on the surface of the Mars from GCR particles during minimum solar activity is about 0.7 mSv/day.
Radiation on the surface of the Mars from GCR particles during maximum solar activity is about 0.3 mSv/day.
Radiation in Earth's orbit from GCR particles during periods of minimum solar activity is about 3.0 mSv/day.
Radiation in Earth's orbit from GCR particles during periods of maximum solar activity is about 0.3 mSv/day.

Radiation on the Earth's surface from SPE at high latitudes can reach more than 1 mSv per flare.
Radiation in Earth's orbit from SPE can reach about 5000 - 50000 mSv per flare.
During the flare on February 23, 1956, the radiation level in Earth's orbit was 5000 mSv.
During the flare on August 16, 1989, the radiation level in Earth's orbit was 50000 mSv.

The ISS walls (an aluminum hull from 5 to 10 cm thick). Astronauts wear personal dosimeters for monitoring.
Radiation inside the ISS during periods of minimum solar activity is about 0.7 mSv/day
Radiation inside the ISS during periods of maximum solar activity is about 0.4 mSv/day
