Although the radiative effects of energetic charged particles of solar or cosmic ray may not directly negatively impact the biosphere because of shielding by the atmosphere, their increasing entry into the atmosphere during geomagnetic field transitions can lead to an increase of ozone loss, and an increasing penetration of solar UVR to the Earth’s surface [7]. On one hand, solar UVR can produce a multitude of harmful effects on cells including alteration in the structures of DNA and other biologically relevant molecules, chronic depression of key physiological processes, and acute physiological stress.
