How It Works

1 RADIOACTIV­E SOURCE RADIOACTIV­E MUTATION

How exposure to radiation can trigger genetic mutations

-

When radioactiv­e sources such as uranium decay, they release high-energy particles.

3 INTRUDER

Once inside the nucleus, radioactiv­e particles damage the double-helix structure of DNA.

2 INFILTRATI­ON

Some radioactiv­e particles can break through the membranes of cells and penetrate the cells’ nuclei.

4 DNA DAMAGE

Once the sequence of nucleotide­s is damaged, the transcript­ion of the informatio­n when the cell divides will be altered.

5 CANCER GROWTH

Mutations can cause the accelerati­on of cell division without the occurrence of natural cell death.

6 TUMOUR FORMATION

As the mass of cancerous cells increases, tumours begin to form.
