🔍 Key Concepts

• Microwave radiation safety limits set by U.S. public health agencies • Typical power density levels that are considered safe for occupational vs. general public exposure • Scale of the answer choices: note the difference between thousandths, hundredths, tenths, and whole milliwatts per square centimeter

💭 Think About

• Compare the numbers to what you would expect near common microwave or radar equipment: would health limits be very large or quite small? • Which of these values seems more realistic for a long‑term exposure limit meant to prevent heating of human tissue? • Think about orders of magnitude: is a difference of 1,000x in allowed exposure (between the smallest and largest option) likely for a safety standard?

✅ Before You Answer

• Verify which answer is in the same order of magnitude as known microwave exposure limits used for safety guidelines • Check that the value you pick would be conservative enough to protect someone who might stand near radar repeatedly over time • Eliminate options that seem too high to be a safe health limit for continuous or repeated human exposure
