Chernobyl Health Effects

1-1. May 10, 2000

1-2. The nuclear radiation and waste can travel over air and make some food harmful to eat.

1-3. In the fish around Norway.

1-4. In the first few years of the explosion, caesium was found in ‘foodstuffs’ and water.

1-5. Because scientists say the caesium is becoming immersed in the soil.

1-6. It’s because of a concentration gradient, pushing the soil into the water, etc.

1-7. For another 10 to 15 years.

1-8. They will remain restricted for about 50 years more.

2-1. These are the children that are victims of Chernobyl radiation. They were born to parents working at the nuclear reactor.

2-2. Members of clean up teams who were sent in after the nuclear reactor exploded.

2-3. Because they contain a higher amount of radiation in their bodies.

2-4. The internal controls were the children’s siblings that were in the womb during the explosion. The external controls were families that were not exposed to the radiation.

2-5. The DNA could have been changed by the children themselves, but scientists reject this theory.

2-6. A change could be because of somatic mutation in the children conceived after parental exposure.

3-1. Low doses are typically no problem, but high doses can kill cells in the body. The rule applies for organs and DNA as well.

3-2. All acute health victims were immediately sent to hospitals- some died as well.

3-3. Late health effects usually grow in people gradually and is mostly unnoticeable at first.
