2. Index
● Unit of measurement
● Effect of radiation exposure on human health
● Major radiation exposure in Hiroshima and
Nagasaki
● Major radiation exposure in Chernobyl
● Medical treatment

3. Unit of measurement
● The unit used to measure radiation dosage is the
rem, which stands for roentgen equivalent in man.
● It represents the amount of radiation needed to
produce a particular amount of damage to living
tissue.
● The total dose of rems determines how much
harm a person suffers.

4. Effect of radiation exposure on
human health
● The radiation has a big influence on people's
bodies.
For example
● Nausea
● Vomiting
● Headache
● Some loss of white blood cells

5. Major radiation exposure in Hiroshima
and Nagasaki
● Many people at Hiroshima and Nagasaki died not
directly from the actual explosion, but from the
radiation released as a result of the explosion.
● Several days after the bombs exploded, doctors
learned that they were treating the effects of
radiation exposure.
● We knew nothing about its cause or cure.

6. Major radiation exposure in Chernobyl
● The explosion was chemical, driven by gases and
steam generated by the core runaway, not by
nuclear reactions.
● Chernobyl release polluted the countryside much
more than ten Hiroshimas would have done.
● People are dying from the radiation caused by the
Chernobyl accident. The estimated total number
of deaths will be 16,000.

7. Medical treatment
● There is currently no effective medical treatment
available for potentially fatal radiation doses.
● Medical science has no way of telling the
difference between people who have received
fatal doses and will die despite all efforts and
others who received less radiation and can be
saved.
