Grade will be a group grade – pick your partners wisely! Grade for notes taken during presentations. Test over 17 and 18 Nov. 20th


5 Middletown, PA 1979

6 How it happened… Non-nuclear portion of plant had a pump malfunction. This caused pressure to build in nuclear part A valve was opened to release pressure and was stuck open, allowing coolant to leak out. Reactor core overheated, started meltdown, but did not breach containment building.

12 Radiation spread over 1000km

13 Health effects Only 1 person died in explosion 44 within a week Thousands have been affected since –Thyroid cancer in 1978-1986 = 5 cases of childhood thyroid cancer. –1986-1998 = 600 cases !

14 Read Silently 19 years ago, Chernobyl exploded, vomiting 8 tons of radioactive ash into the air which swept across the lands poisoning 25% of the population and 25% of the lands of Belarus. And now the new generation of children bears its legacy through a horrifying and bewildering array of afflictions. Some children are born brain-damaged, others have genetic, physiological, neurological and psychological damage.
