What happens to living organisms if they stay outside the earth’s magnetic field for a long time?

The Earth’s magnetic field changes the trajectory of space particles and concentrates their energy at the poles. These particles have high energy and are capable of ionizing (knocking electrons out of atoms) the substance through which they pass. Living cells suffer from ionization, because their structure changes, DNA is damaged, etc. With high radiation, living cells die, therefore, an organism that consists of these cells will not live long if it is exposed to high-energy radiation.
