Gabe, Andrew, and Raphael
4,492 miles away from you...
Big Questions
1. What happened?
2. What were the consequences?
3. How did Russia respond?
What Happened
• Result of safety demonstrationo Closed steam valveso Shut
down safety systems
What happened (cont.)
• Rodso Only 7
• Re-inserted graphite
rods, power jumped • Steam blew hole, hydrogen
exploded
Containment
• Wasn't much to do • Put out fire
o Watero Clay, lead, and
boron • Clear people away
What Went Wrong
• Graphite Control Rods • Building Design
• Personnel
o Decision?
Immediate Effects
• 2 died • Radioactive Fire
• Relocation• 5,500,000
sieverts of radiation released
How Word Got Out
• April 28: Swedish monitoring stations reported abnormally high levels of radioactivity
• Demanded explanation
How Word Got Out
• Government tried cover-up• Then admitted there was a problem to world
Who was affected and How
• 31 people were killed• Food that was contaminated had to be banned
Who was affected and How
• 24 people disabled • 238 suffered acute radiation syndrome• 600,000 significantly exposed
Long Term Effects
• Contaminated land • Death and radiation
sickness • Cancer
• Agricultural
How It Affected Us
• Fallout was registered in all Northern Hemisphere• Not strong enough to affect human health
Is Radiation Still There Today?
• Radiation still part of living there• Still danger of radiation leakage
Is Radiation Still There Today?
• Workers there still check hands + feet for radioactive contamination at end of day
What We've Learned
• Pilgrim Planto Better Building
o More safety systems
o No hydrogen
