1. What does utilitarianism tell us about this case? What do rights and duty ethics tell us? Consider these questions from the point of view of a design engineer who must work on a product that might emit hazardous radiation. Which ethical theory applies best in this case? What does the code of ethics of the IEEE tell us about this case?

2. Analyze this case by determining the factual issues, determining the conceptual issues, and deciding which moral issues apply. Hint: This case is a perfect instance of what we discussed previously in this chapter when we said that the factual issues can be controversial.

3. If there are potential, but not well-understood, hazards in building a product, what are the future consequences of doing nothing, i.e., of making no changes in the design? Will warnings to the consumer suffi ce to get the designer off the hook? Must the product be engineered to be totally safe at all costs?
