As a nuclear engineer who worked on submarines, a part of the job is lowering radiation exposure or risk for the navy (the customer who works on the product). This means understanding the nature of the problem or radiation. You can mitigate the risk of exposure with time, distance and shielding. This means helping the navy develop a plan to do jobs in high radiation areas so they can minimize time, maximize distance, and have shielding in place to lower the radiation levels. This means planning jobs and mapping out the area so they are aware of the areas to avoid, and position their body during work to ensure the exposure is minimized. This also means planning an efficient job so the time is cut down. The navy also needs help as far as knowing the correct material and amount of shielding to put in place.
