The time interval between radiation exposure and symptom onset is called ...

• A. Latent period.
• B. Ionization.
• C. Magnification.
• D. Lead apron.

Answer: (A)

The time between radiation exposure and the appearance of symptoms is called the latent period. In radiation biology, some effects show up right away, but many outcomes—especially cancers or late tissue damage—don’t become evident until months or years after exposure, which is captured by this term. Ionization describes how radiation creates charged particles, not a timing interval. Magnification relates to image size, not biology. A lead apron is protective equipment, not a concept about when symptoms appear.
