Researchers explain what this means and whether tropical fruits should be cut out of your diet.
Radiation is energy that travels from point to point in the form of waves or particles. In fact, we are daily exposed to radiation from various sources, both natural and artificial, writes Science Alert.
The mere mention of the word “radiation” is often associated in people with fear and negative emotions. Others associate exposure to radiation with comics – for example, a small exposure can turn a person into someone like the Hulk.

A lot of noise has also been made by the assertion that the food we eat, in particular bananas, is also radioactive. Scientists hastened to fill this gap in the knowledge of society and explain what natural radiation is and how often we encounter it in everyday life.
In essence, cosmic radiation from the Sun and space, rocks and soil, as well as radioactivity in the air we breathe and the food we eat are all sources of natural radiation.
According to Sarah Loughran, a scientist at the University of Wollongong, bananas are indeed radioactive – in fact, this is a typical example of natural radiation. These tropical fruits contain a lot of potassium, but only a small amount is radioactive. The researcher notes that there is no point in giving up your favorite banana smoothie – the amount of radiation is so small that it is many times less than the background radiation that we are exposed to daily.
Note that there is no difference between artificial radiation, for example, during medical procedures, x-rays or transmission lines, and natural. The harmful effects of radiation are not inherently related to the source of radiation, but to its dose.
The researchers say it is important to remember that radiation is not always dangerous – the harm depends on the type, strength and time of exposure. As a rule, the higher the energy level of the radiation, the higher the probability of damage. In addition, it is important to be aware of its benefits – for example, its use in modern medicine.
