Respuesta :
Pu-239 is regarded as the radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time
Disposal of radioactive nuclear waste is often regarded as a problem.
The waste sources are:
- Nuclear power reactors
- Bomb-related nuclear material
Disposal of bomb-grade plutonium is often difficult.
The longer lived isotopes are:
- Plutonium-239 whose t1/2 is 24,110 years,
- Plutonium-240 whose t1/2 is 6,540 years,
- Curium-245 whose t1/2 is 8,500 years. etc.
The storage of the longer lived elements is through containment for the next several thousand of years.
The control or management of radioactive waste is a hard, multifaceted procedure.
