What does gamma radiation do to the human body?

Gamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA.

What are the symptoms of gamma radiation?

These symptoms include loss of appetite, fatigue, fever, nausea, vomiting, diarrhea, and possibly even seizures and coma. This seriously ill stage may last from a few hours up to several months. People who receive a high radiation dose also can have skin damage.

Can gamma rays cause radiation poisoning?

Exposure from x-rays or gamma rays is measured in units of roentgens. For example: Total body exposure of 100 roentgens/rad or 1 Gray unit (Gy) causes radiation sickness. Total body exposure of 400 roentgens/rad (or 4 Gy) causes radiation sickness and death in half of the individuals who are exposed.

What radiation poisoning feels like?

Symptoms are extreme nervousness and confusion; severe nausea, vomiting, and watery diarrhea; loss of consciousness; and burning sensations of the skin. Onset occurs within minutes of exposure. Stage lasts for minutes to hours.

Which part of the body is most sensitive to radiation?

Lymphocytes (white blood cells) and cells which produce blood are constantly regenerating, and are, therefore, the most sensitive. Reproductive and gastrointestinal cells are not regenerating as quickly and are less sensitive. The nerve and muscle cells are the slowest to regenerate and are the least sensitive cells.

What are some harmful effects of gamma rays?

Dangers and Uses of Gamma Rays The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.

What do you take for radiation poisoning?

You’ll take potassium iodide before or right after you’re exposed to radioactive iodine. You could also take it 3 to 4 hours after, but it won’t be as effective. It’s important to take the medication once a day until the risk of radiation exposure no longer exists.

Can you catch radiation poisoning from another person?

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.

How do you stop gamma radiation?

There are three types of radiation: alpha particles, beta particles and gamma rays. Beta particles can be blocked by a sheet of aluminum, but gamma rays require several inches of lead, concrete or steel to be stopped.

What causes gamma radiation?

They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.

Can you taste radiation?

Metallic taste is a common side-effect of chemotherapy and radiation. Many patients experience taste changes during and after treatment, that are often described as metallic. Metallic taste can make even your favorite foods taste unpleasant.

How do you cure radiation poisoning?

There is no cure, but barriers can prevent exposure and some medications may remove some radiation from the body. Anyone who believes they have been exposed to radiation should seek medical attention as soon as possible.
