Recall that changes occurring within atoms and nuclei can generate and absorb a wide frequency range of radiations.
Describe the highly hazardous effects of ultraviolet waves, X-rays, and gamma rays on human bodily tissues.
Explain how atoms are transformed into positively charged ions upon the loss of their outer electrons due to ionizing radiation.
Understand the concept of radiation dose (measured in Sieverts) as an indicator of the risk of bodily harm resulting from radiation exposure.
Describe how ionizing radiation can alter cellular DNA, leading to gene mutations, cancer, or conversely, be utilized to destroy existing cancer cells.
Interpret simple statistical measures of risk to comprehend the probability of harm from varying types of radiation.
Discuss common safety precautions required to reduce risks, and explain why perceived risks often differ significantly from scientifically measured risks.
