mutagenic nature of radiation (1 Viewer)

[MiSSi]

hey,
need help on discuss evidence for the mutagenic nature of radiation. thanks

I have some info on that:

- The danger of ionising radiation became apparent after the discovery of X-rays in 1895.

- Most of the first generation of radiation therapists in the early 1900s died of cancer.

- The effects of UV radiation have also been known for some time. In 1905, cases of skin cancer were recorded on the necks of grape pickers who were exposed to the sun for long periods.

- Further evidence for the mutagenic nature of ionising radiation came with the development of nuclear weapons (atomic bomb on Hiroshima) and nuclear reactors (Chernobyl disaster). In both these areas, there has been an increase in the frequency of cancers, particularly leukemia.

Hope that helped.

you also should know why radiation is useful in treatment, but not in diagnosis of diseases (eg. cancer) and explain why...

nekkid serpent... i had almost exactly that....you could use the example of the radiation therapist who tested his equipment by 'lighting' his hand every day...then he got cancer of the hand and died. For some reason that makes me laugh but really its horrible

i thought they use different types of radiation for diagnosis, as opposed to treatment. hmm getting confused...
