Answer:
Gamma rays are widely used in medicine and specifically in the area of oncology to treat malignant and cancerous tumors during a process called gamma knife surgery. In this type of treatment, concentrated beams of gamma rays are directed at tumors in order to kill cancerous cells
Explanation:

An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. The nucleus of an atom contains protons and neutrons.

Answer:
- Gamma radiations are used in medical applications to destroy cancerous tumours because beams of gamma rays, called a gamma knife, can be used to kill the cancerous tumour deep inside the body; these beams are aimed at the tumour from many different directions to maximise the dose on the tumour but to minimise the dose on the surrounding soft tissue.
- An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. The nucleus of an atom contains protons and neutrons.
