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.
Effect of radiation exposure onhuman health● The radiation has a big influence on peoples bodies.For example● Nausea● Vomiting● Headache● Some loss of white blood cells
Major radiation exposure in Hiroshimaand 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.
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.
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.
