Can humans be radioactive?
Yes, our bodies are naturally radioactive, because we eat, drink, and breathe radioactive substances that are naturally present in the environment. The major one that produces penetrating gamma radiation that can escape from the body is a radioactive isotope of potassium, called potassium-40.
Are bananas radioactive?
Some potassium is always taken in via the diet, and some is always excreted, meaning that there is no buildup of radioactive potassium. So, while bananas are indeed radioactive, the dose of radioactivity they deliver does not pose a risk.
What does Radioactive do to the human body?
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.
Can a dead body emit radiation?
Human remains containing radiopharmaceuticals, which are buried in a grave or interred in a mausoleum crypt, pose negligible radiation risks to persons handling the coffin or in the vicinity of the burial site or mausoleum. There are several types of radiation that can be emitted from radioactive substances.
How do you bury radioactive bodies?
CDC’s guidelines recommend burial of a body with internal radioactive material in a container designed to keep ground water out. If neither rain nor ground water come into contact with the body, no radioactive material will be leaked into the environment. The family should select a grave site above the water table.
Which radioactive element is present in all dead bodies?

What does decontamination accomplish?
A process used to reduce, remove, or neutralize radiological, chemical, or biological contamination to reduce the risk of exposure.
What is the radioactive symbol?
In Unicode. U+2622 ☢ RADIOACTIVE SIGN (HTML ☢ ) The international radiation symbol (also known as the trefoil) first appeared in 1946, at the University of California, Berkeley Radiation Laboratory. At the time, it was rendered as magenta, and was set on a blue background.
