If you mean to prevent fission, the best way is to keep it in small amounts well separated, and never allow it to be immersed in water, which might create a critical assembly
Pour water over it.

Radioactive material refers to substances that emit radiation spontaneously, while nuclear material is any material that can undergo nuclear reactions such as fission or fusion. Essentially, all radioactive material is nuclear material, but not all nuclear material is necessarily radioactive.
All material uses nuclear energy.

Organisms belonging to the domain Archaea have cells with nuclear material that lacks a nuclear membrane. This type of genetic material organization is referred to as a nucleoid.
These are wastes emitting nuclear radiations.
All material uses nuclear energy.
To deactivate a magnet, you can expose it to high temperatures or strong magnetic fields in the opposite direction to its current polarity. This can disrupt the alignment of the magnetic domains within the material, reducing or eliminating its magnetic properties.
The nuclear hazards are caused by nuclear material. It is present in different parts of world.
Duplicated nuclear material is called chromatin.
Producing weaponized uranium and nuclear material from which nuclear bombs can be built.
