Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.14-Apr-2021

Should I be worried about radiation exposure?

In large doses, radiation can cause serious tissue damage and increase a person's risk of later developing cancer. The low doses of radiation used for imaging tests might increase a person's cancer risk slightly, but it's important to put this risk into perspective.

What is the exposure of radiation?

Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air.

What should you do to monitor your exposure to radiation?

External exposure to radiation is measured with dosimeters worn on the person. These dosimeters can measure both the penetrating (whole body) dose and the shallow, non-penetrating (skin) dose to the entire body, lens of the eye and extremities (hands).

What are the side effects of being exposed to radiation?

Possible symptoms include:

• Nausea and vomiting.
• Diarrhea.
• Headache.
• Fever.
• Dizziness and disorientation.
• Weakness and fatigue.
• Hair loss.
• Bloody vomit and stools from internal bleeding.

How much radiation does a phone give off?

The Federal Communications Commission (FCC) — which regulates cell phones, among other things, in the United States — has set radiation standards for cell phones at 1.6 watts per kilogram averaged over 1 gram of tissue.

How much radiation is safe for humans?

Adult: 5,000 Millirems. The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is "as low as reasonably achievable; however, not to exceed 5,000 millirems" above the 300+ millirems of natural sources of radiation and any medical radiation.

Can radiation be passed from person to 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.

Why do we get exposed to radiation?

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.

Is radiation sickness contagious?

Radiation is not contagious, not in the usual sense that one can “catch” certain diseases by being exposed to someone with the illness.
