Chronic dose is best described as

Chronic dose is best described as

• A. Absorption of relatively small amounts of radiation daily over a long period
• B. A single high dose
• C. The energy deposited during a very short exposure
• D. The dose rate at the time of exposure

Answer: (A)

Chronic dose refers to long-term exposure where energy is deposited in small amounts over time, so the total dose builds up gradually. This means absorbing relatively small amounts of radiation daily over a long period, which accumulates to a meaningful total dose. A single high dose or energy deposited during a very short exposure describes acute exposure, not chronic. The dose rate at the time of exposure is about how fast the dose is delivered, not the accumulated amount over time.
