Nuclear radiation is one invisible killer.

The absorption of ultraviolet radiation by the ozone layer help to sustain life because it helps to protect living things from damage of solar radiation.
Nuclear radiation doesn't affect the ocean itself, but the animals that live there. Just like any living thing, if an ocean animal is exposed to high level of radiations it might develop mutations, and/or cancer, leading to a painful death.
I'm not sure this is really a meaningful question. It's a source of gamma rays, so if you need those, there you go. It also produces alpha and beta rays (depending on the exact nuclear decay involved), so again, if you need those, extremely useful.
nuclear what? nuclear radiation affects virtually all living things. it is poisonous to virtually everything as it kills living cells and just like in a microwave oven which uses the same technology it will cook you from the inside out.
Robots are at risk of damage from radiation in space. However, they are at less risk than living creatures because they don't have DNA.
Nuclear radiation is one invisible killer.
There are many forms of radiation. The radiation people usually think of is the radiation associated with nuclear decay; the radiation that comes from an X-ray machine or a nuclear bomb. However, radiation includes thermal radiation. This is the emission of heat. Since almost all chemical reactions result in the production of heat, and the metabolism of any living creature is essentially a very complex inter-related series of chemical reactions, all living creatures emit radiation: Living creatures require food ---> Food is broken down into nutrients and absorbed (this is a chemical reaction) ---> Chemical reactions generally produce heat ---> Living creatures radiate heat ---> Living creatures emit radiation
Nuclear power plants do not normally give off radiation that can be detected, but then can have accidental leaks of radioactive materials which, in turn give off radiation. These can get into the environment and be dispersed, eventually causing damage. Probably the most common radioactive substance to get out of nuclear power plants in leaks is tritium. Tritium emits beta radiation with a rather low energy (as beta radiation goes). This means that it cannot penetrate skin deeply enough to damage living cells. The problem is that the tritium is bound in tritiated water and this can be ingested or inhaled, and the tritium winds up being incorporated into the body, where it can do damage. Internally, low energy beta radiation is as damaging as high energy, because the damage is done as the radiation slows down. More than a quarter of the nuclear power plants in the United States are known to be leaking tritium. The Nuclear Regulatory Commission says this is not sufficiently important to close the plants. Other kinds of leaks can release other kinds of materials. When fission occurs, as it does in the nuclear reactor fuel, there is a wide variety of fission fragments that are produced. These are all different in the types and powers of radiation produced. So they will radiate alpha, beta, and gamma particles, along with neutrons - all forms of ionizing radiation and all dangerous. This is true for both low level and high level nuclear waste.
Scientists who study radiation are called radiologists or radiobiologists. They specialize in the diagnosis and treatment of diseases using radiation, as well as studying the effects of radiation on living organisms.
Radiation, even in small doses, can cause cancer in humans and other living things Alpha radiation is responsible for most of the damage of DNA in living cells

The Ultra Violet radiation is the harmful radiation. It can cause skin cancer, eye cataract etc.

Radium emits alpha, beta, and gamma radiation. Alpha radiation is fully ionized helium nuclei. Beta radiation is high energy electrons. Gamma radiation is very high energy electromagnetic radiation. All of these can do significant damage to living things.
