Radioactive Decay

• What is the process called when unstable atomic nuclei decay?

  Radioactive decay
• What happens to nuclei during radioactive decay?

  They give out radiation and become stable
• What is the nature of the decay process?

  It is a random process
• How is activity measured in radioactive decay?

  In becquerels (Bq)
• What does count-rate refer to in radioactive decay?

  Number of decays recorded each second
• What happens when radiation strikes an atom?

  It can knock off outer electrons
• What is the effect of increased ionization from radiation?

  Higher likelihood of causing harm to cells
• What can result from cell mutation or death due to radiation?

  Cancer if cells are continuously exposed
• What can continuous exposure to high doses of radiation lead to?

  Cancer
• What is the relationship between radiation and cell mutation?

  Radiation can cause mutations in cells
• How does the likelihood of harm from radiation change with increased ionization?

  It increases with more ionization
• What is the consequence of radiation interacting with our cells?

  It can lead to cell mutation or death
• What is the effect of high doses of radiation on cells?

  It can cause cell death
• What happens to cells that are continuously exposed to radiation?

  They are more likely to develop cancer
• What is the risk associated with high doses of radiation exposure?

  Increased risk of cancer development
