The main idea here is that the most effective way to limit radiation exposure is through three basic controls: time, distance, and shielding. Keeping the time you spend near the source as short as possible reduces the total dose you receive. Increasing your distance from the source makes a big difference because radiation intensity drops rapidly with distance—doubling the distance cuts exposure to about a quarter. Shielding adds a physical barrier between you and the source, absorbing or scattering radiation so less reaches you, with the material chosen based on the type of radiation involved. In practice you combine these approaches: shorten exposure time, step back when possible, and use appropriate shielding to stand between you and the source. PPE and monitoring are important tools, but PPE alone doesn’t reduce exposure as effectively as time, distance, and shielding, and monitoring is about measuring dose rather than protecting you.
