  •  
    • WHAT IS NUCLEAR WASTE?
    • Nuclear waste: is the remains of radioactive decay, or nuclear fission.
    • HOW IS IT MADE?
    • Nuclear waste is made mostly by radioactive decay.
    • What is radioactive decay?
    • Its the process in which radioactive isotopes release gamma rays and lose particles.
    • There are 3 types of radio active decay:alpha, Beta, and gamma.

  •  
    • Can Nuclear waste affect our health?
    • Yes, in a number of ways. One of the largest dangers is that radioactivity is a carcinogen.
    • A carcinogen is a substance that causes cancer.
    • It also affects our DNA.
    • How does it affect our DNA?
    • It affects our DNA in 2 main ways:
    • 1. Isotopes push an electron out of its orbit, if this electron strikes the DNA, it damages it.
    • 2. if this electron collides with a water molecule, it becomes an isotope, damaging your DNA.
    • All this takes less than 1 second.
    • Radioactivity relesed from nuclear waste can also damage body cells.
    • HOW?
    • The electrons can ionize the cell, making it “decay”
    • Or it can stop the cell from reproducing.
    • But then how do scientists that handle nuclear waste survive?
    • They wear special suits, that reflect gamma radiation.
  • Like this
  • SO DON’T DO THIS:
  • LEAVE IT TO THESE GUYS:
  • Otherwise its….
