How does radiation cause mutation?

Answer 1

Radiation can transfer energy to molecules such as DNA that causes bonds to break.

Radiation can be seen as a package of energy. This can be a particle (such as #alpha# and #beta# radiation) or it can be a wave / photon (#gamma# / X-ray).

In any case, radiation loses energy when it interacts with molecules within the cell. Radiation that is strong enough to liberate an electron from an atom is referred to as ionizing radiation; this is in contrast to other forms of radiation, such as light and microwaves, which have a lower energy.

Bonds can break when an electron leaves a molecule. Radiation can induce mutations in two ways:

Radiation can cause mutations by damaging the DNA within cells. This damage can result in changes to the DNA sequence, which can lead to mutations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
