Moj odgovor osobi koja je zabrinuta na X-ray na pluca!
Perhaps surprisingly, radiation is a natural part of our environment. None of us can avoid being exposed to radiation. We are exposed to it all the time, everywhere we go. This naturally occuring radiation is known as "background radiation".
In the UK, the majority of the background radiation we absorb comes from radon gas (roughly 58 per cent), which seeps out of the ground. Another 16 per cent comes directly from rocks in the ground, while 14 per cent streams down on us from cosmic rays and the final 12 per cent comes from the food we eat.
To put the risks of radiation from X-rays into perspective: a four-hour airline flight will expose you to the same amount of radiation (from cosmic rays) as from a simple chest X-ray. This is the same as the amount of radiation we would be exposed to naturally (from background radiation) over 10 days.
These days high-quality X-ray pictures can be produced from very small doses of radiation. This helps to minimise the risk of developing cancer as much as possible.
Ukratko radijacija plucne slike je kao exposure za desed dana na zemaljske radijacije ili kao avionski let 4 sata ,koji nas expoza radijaciji cosmickih zraka.
