Question

Why is nuclear waste enclosed in lead and cement casks and buried deep under ground?


The cement makes the nuclear material inert.

The lead, cement and deep earth cover act as radiation shields.

The cement reacts with the waste to initiate the nuclear process.

The cement takes on the properties of the fuel, creating more fuel.

Answer 1

What do you think?
I 'll give you a hint - the radiation from nuclear waste is extremely hazardous - if not disposed off properly and the radiation reaches us - it can be deadly.

Now think

Answer 2

The lead, cement and deep earth cover act as radiation shields.

Answer 3

Correct..

Answer 4

Which of the following statements is correct regarding spent fuel rods?


They are no longer radioactive.

They contain only one type of isotope of the fuel (uranium).

They usually remain radioactive for less than 100 years.

They are scheduled for deep underground burial.

its the third choice?

Answer 5

its extreme radioactivity !!

Answer 6

high radiation hazard as i mentioned - so extremely radioactive.

Answer 7

They usually remain radioactive for less than 100 years.?
so that is the answer ^^^

Answer 8

No. They actually radiate energy for much more than 100 years - 1000s of years in fact - so the must be buried deep underground - which is also what your previous question was all about.

Answer 9

oh okay

Answer 10

This is a way of remediation - the solidification method which involves the encapsulation of a highly toxic contaminant in a monolithic solid with high structural integrity. This method is used when the contaminant cannot be destroyed. Thus, it is made unavailable to the environment. Another advantage is that it provides a more stable soil structure for future constructions..
