4.Chemical waste 「水俁病」(Minamata disease) The best known example of heavy metal pollution in the oceans took place in 1938 when a Japanese factory discharged a significant amount of mercury metal into Minamata Bay, contaminating the fish stocks there. 5.Radioactive waste People view radioacti...
The UK has significant holdings of long lived radioactive waste that will remain potentially hazardous for many thousands of years. Previous attempts to dispose of these wastes have ended in failure. The most recent attempt ended with a refusal from the Secretary of State for the Environment to ...
To keep these chain reactions in check, power plants cool the nuclear cores, typically with water. However, the process creates a significant amount of nuclear waste, such as uranium tail millings, spent reactor fuel and radioactive waste that can be hazardous to both people and the ...
Superman is an alien, Ms Marvel has alien genes, and Spiderman and the Hulk are bothcontaminated– or poisoned – by radioactive substances that change their DNA. Neil What about Batman and Iron Man? They're just ordinary guys with a lo...
not stable," said Stanford University's Dr. ... "Glass is soluble and it's leachable-it's what you would do if you wanted to maximize activity in the geologic environment," Luth said. New findings are also being reported on the use of salt mines as repositories for radioactive waste....
题目Nuclear power(核能)factories make power by using a special course called nuclear fission(核裂变).While this course is of great help in making clean energy,it also leads to a type of waste(废料)called nuclear wastewater.It has radioactive(有辐射的)materials.The nuclear wa...
Radon mitigation is an important consideration in green building design, especially in areas prone to high radon levels. Radon, a naturally occurring radioactive gas, can pose serious health risks if it accumulates indoors. Green buildings incorporate radon mitigation strategies to ensure the safety an...
Nuclear power is a deeply controversial subject, and many scientists have disputed its benefits. Although nuclear power derived from fission can provide reliable, inexpensive electricity without greenhouse gases, it also produces highly radioactive waste that must be stored for thousands of years. Some...
