It’s natural and all around us. It comes up from the ground, down through the atmosphere, and even from within our own bodies. It can be man-made too. But it’s nothing new. It’s been present since the birth of the planet. It’s radiation, and radiation is, quite simply, part of our lives.
Naturally-occurring radioactive materials were discovered in 1896. Less than 40 years later, physicists discovered that radioactive elements can be artificially created. Within a decade of this discovery, scientists had split the atom.
These findings allow us to use radioactive materials for beneficial purposes, such as generating electricity and
diagnosing and treating medical problems. For these many benefits, excessive radiation exposure can also threaten our health and the quality of our environment.
Looking at this chart, we can see that Nuclear power contributes minor affect to the world daily radiation.
Basically, there are much more harmful radiation exist in the world that is not contributed by the nuclear power plant.
As we can see the radiation from the nuclear power plant commits the lowest radiation. Even if we live nearby a nuclear reactor. It is not the nuclear power generation is the only source of radiation. Natural sources of radioactivity are all around, and man-made radioactive materials are a vital part of medicine and industry. Exposure to some radiation, natural or manmade, is inevitable. We live with radiation everyday, therefore we must understand both its risks and benefits.
