7.14 describe the dangers of ionising radiations and describe how the associated risks can be reduced.


Radiation can cause mutations in living organisms: radiation can damdge the stucture of a cells DNA, when the cell replicates the changes (mutation) will be passed on; this can be how cancer is caused.

Radiation can damage cells and tissue: atoms can be change by radiation, this prohibits them functioning properly, this can mean cells and so tissue are damaged.

The problems arising in the disposal of radioactive waste: this waste emits radiation that, as shown above, can be dangerous. If the waste is put into water it can poison ecosystems, similarly with land. Radioactive waste tends to be buried under the ground; with the thinking that when it is much less harmful it can be dug up and disposed of.

  4. Precautions: - wear protective clothing i.e. lead apron, - keep exposure time to a minimum, - label radioactive sources clearly, - dispose of radioactive waste by burying in non-porous rock and not on a tectonic plate boundary.... these are all from my teacher so are reliable :)
