A notable category is a type of EMR that is emitted from black holes, supernovae, pulsars and especially the sun. Generally, cosmic radiation may cause harmful interactions with other types of radiation.
Can we really do anything to protect ourselves from this?
It is interesting to note that in the 1960’s, NASA did a study into what would best protect the astronauts from Beta Gamma Cosmic Radiation. They calculated that if shielding was to be used, the amount of shielding required would be too heavy and bulky and spacecraft would not be able to leave the ground. In the end NASA opted for a harmonising technology called a Helmholtzer Coil to balance the energy. Interestingly this works on exactly the same principal as the Geoclense!!
