The major sources of nuclear waste

Nuclear medicine

Cooled pools

Short-lived waste

Long-lived waste

Very short-lived waste

The different types of radioactive waste

Loses half of its radioactivity over a period of less than or equal to 31 years

Loses its radioactivity in less than 100 days

Loses its radioactivity over a period of more than 31 years

In France, radioactive waste is rigorously managed according to four principles

Classification

  • Level of radioactivity

  • The duration of radioactive activity

Control and classification of radioactive waste

Control

Mutations

a dose of 1 sievert carries a 5,5% risk of developping cancer

The sievert is the unit used to give an evaluation of the impact of radiation on humans

The impact of radiation on humans
