Radiation sickness is:

Radiation sickness is:

• A. Infection caused by bacteria.
• B. Illness and symptoms resulting from excessive exposure to ionizing radiation.
• C. An allergic reaction to dust.
• D. Poisoning from chemicals.

Answer: (B)

Radiation sickness happens when the body is exposed to large amounts of ionizing radiation, which damages many cells. This can trigger acute radiation syndrome, with early symptoms like nausea and vomiting soon after exposure, followed by fatigue. As the dose is higher, bone marrow function is suppressed, raising the risk of infection and bleeding due to low white cells and platelets. Because the problem stems from radiation exposure itself, not from bacteria, dust, or chemical poisoning, this illness isn’t contagious and isn’t explained by infection, allergy, or chemical toxicity. In short, it is illness and symptoms resulting from excessive exposure to ionizing radiation.
