Final answer:
It is true that radioactive liquids must not be poured down laboratory drains, as this can lead to environmental contamination and pose serious safety risks. Radioactive waste requires proper containment and disposal in accordance with strict regulations.
Step-by-step explanation:
True, you cannot pour radioactive liquids down any laboratory drains. In a laboratory environment, it's vital to follow strict safety protocols to ensure not only your safety but also the wellbeing of others. Radioactive materials can be incredibly hazardous if not handled and disposed of correctly. In the case of radioactive liquids, they must be contained and disposed of according to specific regulations to prevent contamination of the water supply or the environment. When working in the lab, it is important to be aware that different water systems, such as those in a condenser, steam generator, and reactor, do not mix with each other.
The water in the reactor section is typically radioactive and is therefore contained within a containment structure for safety reasons. Similarly, any waste containing radioactive substances must be handled meticulously to prevent leaks or spills which can have dangerous consequences as demonstrated by environmental disasters like the Love Canal incident.
