Questions for you to answer: 1. Should an industry have to prove that a product is safe before it is sold? 2. What constitutes "safe", especially as our understanding of the technology changes? 3. Who should pay for safety studies, considering possible industry bias and the limited budgets (and understanding of the technology) of government? 4. Should there be follow-up studies and, if so, how is a decision made about when such studies should be done?
