Complete the analogy. T.V. sets:
electronic waste :: Uranium :​

Answer 1

Answer:Electronic waste or e-waste is one of the emerging problems in developed and developing countries worldwide. It comprises of a multitude of components with valuable materials, some containing toxic substances, that can have an adverse impact on human health and the environment. Previous studies show that India has generated 0.4 million tons of e-waste in 2010 which may increase to 0.5 to 0.6 million tons by 2013–2014. Coupled with lack of appropriate infrastructural facilities and procedures for its disposal and recycling have posed significant importance for e-waste management in India. In general, e-waste is generated through recycling of e-waste and also from dumping of these wastes from other countries. More of these wastes are ending up in dumping yards and recycling centers, posing a new challenge to the environment and policy makers as well. In general electronic gadgets are meant to make our lives happier and simpler, but the toxicity it contains, their disposal and recycling becomes a health nightmare. Most of the users are unaware of the potential negative impact of rapidly increasing use of computers, monitors, and televisions. This review article provides a concise overview of India’s current e-waste scenario, namely magnitude of the problem, environmental and health hazards, current disposal, recycling operations and mechanisms to improve the condition for better environment.

Answer 2

The Correct analogy for Uranium is Radioactive wastes.

• Radioactive waste is also known as Nuclear wastes.
• Nuclear reactors, fuel processing plants, hospitals, rare earth mining and research facilities all produce radioactive waste. Decommissioning and dismantling nuclear reactors and other nuclear plants also create radioactive waste.
• It is divided into three categories: low-level waste (LLW), which contains minimal quantities of mostly short-lived radioactivity, intermediate-level waste (ILW), which contains higher amounts of radioactivity and needs some shielding, and high-level waste (HLW), which is highly radioactive and warm due to decay heat and thus requires to cool down the temperature and proper shielding.
• Uranium fuel that has been used in a nuclear power reactor and is "spent," or no longer useful in creating electricity, is the major kind of high-level radioactive waste.
• Spent fuel is both thermally hot and radioactive, necessitating remote handling and shielding.
• High-level wastes are harmful because they emit lethal radiation doses when exposed to them for short periods of time.
