The reason it isn't safe to jump in water that is contaminated with nuclear waste material is because it can make you sick or even kill you.
Mostly clothing which has been worn in slightly contaminated areas, the activity will be minimal or even zero but it will be dumped as low level waste to avoid the need to check and decontaminate it. Also any other material removed from a contaminated area that carries a small activity, tools or temporary material that has got slightly contaminated.
These are wastes emitting nuclear radiations.
Nuclear fusion produces very little waste compared to nuclear fission. The waste produced by nuclear fusion is mainly low-level radioactive material, which is easier to manage and has a shorter lifespan.
Nuclear energy produces radioactive waste, which is a byproduct of nuclear reactions in power plants. This waste can include spent nuclear fuel, contaminated materials, and other radioactive substances, all of which require safe storage and disposal methods to prevent environmental and health risks.
Nuclear waste can take thousands to millions of years to decay completely, depending on the type of radioactive material.
Radioactive waves
Nuclear waste. Other than that probably plastic because it is not biodegradable.
Radioactive waste is a waste product containing radioactive material. It is usually the product of a nuclear process such as nuclear fission, though industries not directly connected to the nuclear power industry may also produce radioactive waste.
It depends on the waste material. Methods appropriate for chemical hazards would not be so for nuclear waste.
No, lasers would not cause nuclear changes, they would only melt or vaporise material which is not what is wanted. The nuclear properties of the waste would remain the same.
Primarily it is the spent fuel which contains highly active fission products. There will be small amounts of low level waste arising mainly from maintenance operations, this can usually be put into a dry store on the site.
Biological waste is any material that contains or has been contaminated by a biohazardous agent. Biological waste includes, but is not limited to; Petri dishes, surgicalwraps, culture tubes, syringes, needles, blood vials, absorbent material, personal protective equipment and pipette tips
