Explanation:
1. Nuclear waste is extremely harmful for the ecosystem . Nuclear waste damages tissues and cells. Nuclear material is the most poisonous material on earth. It's effects are not easily removed from the environment and is responsible for delivering many side effects.-
For example ,
Leakage caused in the nuclear power plant in Ukraine and in Japan, where 14 people died in Ukraine plant and 14000, had been infected with cancer due to radiation .
It is extremely challenging for the the governments to efficiently dispose of nuclear waste. Exposure to radioactive material causes Cancer birth defect and other abnormality depending on the time and exposure amount of radiation and the decay mechanism.
2. yes , it is one of the best ways to let limited people to enter the nuclear test sites as it is not safe .
3.
Finland is using a different method to dispose the nuclear waste.
They take long tunnels with holes and dispose the nuclear waste rods . And then cover it with clay a and mud forever and close them . The nuclear waste is first sealed in safe containers with insoluble material . And then sealed , it is again steel boxes and once again closed in buffer material, especially designed to absorb the radiation . After this they are disposed in the deep tunnels and never to be disturbed.
