In order to estimate the radiation damage we need to estimate the number of atoms in our path and the damage done by each atom The solar system rotates around the center of the galaxy at a radius of about 10 kiloparsecs or about 3 x 10 4 light years Since 1 ly 3 x 10 8 ms X x 10 7 s 10 16 m the distance traveled is d 3x10 20 m The typical density of interstellar space is 1 atom per See Answer
