Bananas are a sugary fruit, so eating too many and not maintaining proper dental hygiene practices can lead to tooth decay. They also do not contain enough fat or protein to be a healthy meal on their own, or an effective post-workout snack. Eating bananas becomes significantly risky only if you eat too many.
Q. How dangerous is space radiation?
Beyond Low Earth Orbit, space radiation may place astronauts at significant risk for radiation sickness, and increased lifetime risk for cancer, central nervous system effects, and degenerative diseases. 1 mSv of ionizing radiation is equivalent to about three chest x-rays.

Q. What part of a banana is radioactive?
Potassium (K) is a widely encountered element with a very small fraction of its atoms, about 0.012%, being radioactive.
Q. Is it OK to eat the bruised part of a banana?
When the banana’s cells are wounded, as happens during bruising, compartments in the cells leak and polyphenols mix with enzymes. If you see a brown bruise on the peel, but pristine banana flesh underneath, the damage was restricted to the exterior, so go ahead and eat your banana.
Q. How much radiation do you get from flying?
We are exposed to low levels of radiation when we fly. You would be exposed to about 0.035 mSv (3.5 mrem) of cosmic radiation if you were to fly within the United States from the east coast to the west coast. This amount of radiation is less than the amount of radiation we receive from one chest x-ray.
Q. Why flying is bad for your health?
One of the most serious risks of flying happens to be something that doesn’t necessarily require long-haul flights to manifest. “Traveler’s thrombosis,” in which blood clots form during long periods of cramped immobility, usually leads to the clots dissolving in the bloodstream without incident.
Q. How much radiation do you get from international flights?
Astronauts on board the International Space Station could easily be exposed to over 150 mSv. That’s 20 CT scans, 250 mammograms or 7,500 chest X-rays. That’s a lot of radiation, but it takes a dose of 1,000 mSv in a short period of time to induce acute radiation sickness.
Q. Is CT scan high radiation?
Like X-rays and PET scans, CT scans use ionizing radiation, which can damage DNA and cause cancer. Two other imaging technologies, MRI scans and ultrasound, do not use radiation. CTs are used for a plethora of reasons, among them finding kidney stones, evaluating chest pain and detecting tumors or other abnormalities.
