| 1 | ■External Exposure and Internal Exposure What is the difference between external exposure and internal exposure? When radiation comes from a source outside your body, it's called "external exposure." When radioactive materials get inside your body and expose you to radiation, that's "internal exposure."ernal Exposure and Internal Exposure What is the difference between external exposure and internal exposure?

| 2 | ■Three Ways to Reduce External Exposure To reduce external exposure, you can: 1. Keep a safe distance from the radiation source, 2. Use shielding to block the radiation, and 3. Limit the time you spend near the source. |
