Radiation cannot be spread from person to person . Small quantities of radioactive materials occur naturally in the air, drinking water, food and our own bodies. People also can come into contact with radiation through medical procedures, such as X-rays and some cancer treatments.
Can radiation spread by touch?
People who are externally contaminated with radioactive material can contaminate other people or surfaces that they touch. For example, people who have radioactive dust on their clothing may spread the radioactive dust when they sit in chairs or hug other people.
Can a person exposed to radiation become radioactive?
Exposure to radiation does not immediately make a person radioactive . The only type of radiation that is capable of directly causing other material to become radioactive is neutron radiation, which is generally only found inside nuclear reactors or in a nuclear detonation.
What happens if you touch someone who is radioactive?
Initial symptoms include nausea, vomiting, headache and diarrhoea . These symptoms can start within minutes or days after the exposure. People who have been exposed to high doses can also have skin damage ranging from itching to burns, blisters and ulcers. They may also have temporary hair loss.
Can radiation be passed from person to person Chernobyl?

How long can you be exposed to radiation?
Tremors and convulsions will occur 5 to 6 hours after exposure . Within 3 days, there will be coma and death. People who experience repeated doses, or who appear to recover, may have long-term effects.
What does radioactive do to your body?
Ionizing radiation—the kind that minerals, atom bombs and nuclear reactors emit—does one main thing to the human body: it weakens and breaks up DNA , either damaging cells enough to kill them or causing them to mutate in ways that may eventually lead to cancer.
Can I use my cell phone after radioactive iodine?
You will have to stay in your room for at least 1 to 2 hours after your treatment. You can use your cell phone or watch TV to help pass the time . You won’t be able to have visitors during this time. You may not have any side effects from the treatment right after you get it, but you may have side effects later.
What material can protect you from radiation?
This is why lead aprons and blankets are the most effective shielding material to fight off x-rays and gamma-ray. After all, lead has a very high number of protons in each atom (82 to be specific), which makes it a very dense metal shield.

What is the highest amount of radiation a person can take?
The highest recommended limit for radiation exposures is for astronauts- 25,000 millirems per Space Shuttle mission , principally from cosmic rays. This amount is beyond the average 300+ millirems of natural sources of radiation and any medical radiation a person has received.
