Since this a science question: we probably will never eliminate exposure to radiation. Besides the radiation we have caused, there is normal natural tradition. There is also something called background radiation which is part of our world.

∙ 13y agoYes, very slightly. There is a radioisotope of carbon, which occurs naturally, in which the carbon nucleus has two extra neutrons. Normal carbon is "carbon-12"; this radioactive variant is called "carbon-14". As long as we are alive, we take in carbon from the food we eat, and some tiny fraction of this is the "carbon-14" isotope.
Radioactive isotopes decay, and become some other element; in the case of carbon-14, the nucleus emits an electron, one of the neutrons becomes a proton, and the new atom is nitrogen-14. The "half-life" of C-14 is 5,700 years; after 5700 years, half of it will be gone. (After another 5,700 years, half the remainder will be gone.) After death, you stop consuming carbon-14, and over the course of thousands of years, some of it decays away. We can measure the amount of carbon-14 remaining in a sample, and calculate how long it has been dead.
There are many other radioactive elements that are present in the human body. The thyroid gland requires iodine for proper functioning, and if you consume radioactive iodine-131, the intense radiation can cause thyroid cancer or cause your thyroid to stop functioning. Iodine-131 has a half-life of only 8 days, so it decays quite rapidly and is eliminated from the environment after only a few months.
Our bones are primarily made of calcium, but a similar element called strontium can undergo the same sorts of chemical reactions. One of the problems of the fallout of radioactive elements after a nuclear explosion would be radioactive strontium-90; if someone consumed food contaminated with SR-90, it would be absorbed into the bones. SR-90 has a half-life of 29 years, so it isn't all THAT radioactive, but if there were enough consumed it could cause blood or bone cancers or leukemia.

Why does electromagnetic radiation cause cellular damage to humans?
The most common exposure to electromagnetic radiation is from the use of cell phones. It is a minor almost minute exposure. Why it can damage the cell structure of humans is because it is toxic it is simply because it is radiation.
What is the nature and magnitude of radiation risks to humans?
The increased possibility of cancer induction from x-ray radiation exposure.
What is the effect of LD50 30 radiation on human skin?
LD50/30 radiation refers to the dose of radiation required to kill (LD=Lethal Dose) 50% of the test cohort within 30 days. Its normally specified for a particular species, rats, rabbits etc and is thought to be about 3-4 Sieverts in humans. The wikipedia article "Radiation Poisoning" has a table of effects of increasing radiation on humans. Note that at 3-4 Sv there are no skin effects if it is whole body exposure. If it is localised exposure then there will be radiation burns followed by erythema.
How do radiation technicians know when they have been over exposed by radiation?
Radiation personnel wear a small badge containing a film which darkens upon exposure to radiation. These are regularly screened to determine if a dangerous exposure has taken place.
Does Radiation Exposure Gradually decrease over a lifetime?
no

What is radiation exposure safety?
Radiation exposure safety is the process of preventing or minimizing exposure to radiation, and tracking what does occur.
What were the effects of radiation exposure on humans in hiroshima?
The results are called acute radiation syndrome. These begin within a day of exposure. There will be GI tract problems, falling blood counts, neurological signs, even death. You are probably aware of radiation treatment for cancer and the loss of hair.
What is the nature and magnitude of radiation risks to humans?
The increased possibility of cancer induction from x-ray radiation exposure.

What is the effects of Alpha radiation?
The effects differs that what it is effecting if we talk about humans than in general, alpha radiation is of small risk to humans. Compared to its cousins, beta and gamma particles, alpha radiation has an extremely low penetration depth and is often completely blocked by the outer layers of skin or even the surrounding air. Although external exposure poses little to no risk to humans, internal exposure, such as through inhalation or ingestion, can prove to be extremely damaging to the body. It causes cancer kidney damage radiation poisoning
What is another name for radiation exposure badges?
Badges used to measure exposure to ionizing radiation are usually called radiation dosimeter badges.
Radiation symtoms can result from a single exposure and are contagious?
While radiation symptoms can occur from a single, prolonged, exposure, the symptoms of radiation are not contagious.
What are the risks of nuclear radiation?
The exposure to nuclear radiation has many risks associated with it. Cancer, DNA mutations, and radiation poisoning can all occur with any level of radiation exposure.
Can your baby die of radiation exposure?
Yes. Depending on the length of the exposure, radiation can sicken or kill any human.
Identify THREE reasons a person may develope radiation sickness?
repeated exposures to both high-energy radiation and high levels of fallout exposure to high levels of fallout a single exposure to high-energy radiation
What are 3 reasons radiation sickness varies?
Radiation sickness varies depending upon duration of exposure, whether it was an internal or external exposure, and the dosage of radiation.
