Radioactive wastes are generally classified into two categories: high and low level wastes.

High-Level Radioactive Waste (HLRW) refers to most of the waste generated in nuclear reactors. It is a serious threat to anyone who comes near the waste without shielding.

Low-Level Radioactive Waste (LLRW) refers to the less hazardous waste generated by hospitals, research laboratories, and certain industries.
