    Answer:

    Hey

    First, you need to know that radiation is vital for life on earth and the process of photosynthesis. also, you couldn’t see without radiation.

    But some radiation is harmful to DNA such as x-rays and gamma rays. and most of the energy is lost to radiation (created by heat, fission, and fusion).
