I need this fast pls help

It’s kinda blurry can you maybe take another picture ?

Living creatures are made up of mostly organic compounds that contain carbon(c), hydrogen, oxygen(o), and nitrogen(n). If ingested, radioisotopes of these elements may be readily absorbed into the body, and the radiation they produce (beta particles) may ionize molecules they hit, damaging DNA in cells, and disrupting their normal activities. If a lot of these radioisotopes are ingested, the result would be radiation sickness and possibly death.

Every element is known to have a few radioisotopes. Radioisotopes are unstable atoms of an element due to an imbalance between the number of protons and neutrons in the nuclei of their atoms. As a result, such an unstable nucleus may eject a piece of itself in the form of an alpha or a beta particle traveling at a great speed, while the atom itself changes to an atom of a different element due to a change in its number of protons that determines its atomic number.

Afraidsugar lol it’s the third one
