Yes, it has been increasing. It is because of ozone depletion.
Increasing exponentially.
Human nature does not change and an increasing knowledge of the world around us has always been a feature of the human condition. In recent times this knowledge has been increasing at a greater rate than even before. But it seems that we cannot escape from human nature, the propensity of people to do certain things and therefore issues that have been covered by Christianity from the beginning.
No, camera radiation has not been detected in the area.
Radiation is all around us and comes from the sun. Humans have found ways to make some of this radiation. Radiation has been used successfully to treat cancers and is also used in manufacturing, agriculture and in scientific research. Too much radiation is harmful and can also cause some cancers. Overall, radiation produces more benefit than hazard when used properly.
Robots have been sent into Fukushima Daiichi because parts of the plant have radiation levels that exceed safe levels for human entry.
Ionizing radiation, such as X-rays and gamma rays, have enough energy to remove tightly bound electrons from atoms, leading to cellular damage and potential harm to living human tissue. Exposure to high levels of ionizing radiation has been linked to an increased risk of cancer and other health issues.
it has been increasing the last 200 years
Ozone is only useful in the stratosphere, where it blocks about 98% of ultraviolet radiation. This radiation is very harmful to human and plant health. Ozone has been disappearing in stratosphere as a result of chemicals humans have been releasing, though the hole appears to be leveling off now as many of these chemicals have been banned for 20 years.
The carbon content of the Earth's atmosphere has been increasing, particularly in the form of carbon dioxide (CO2) but also in the form of methane (CH4) which will eventually burn and become more carbon dioxide. And, the carbon content of the ocean is also increasing since carbon dioxide has been dissolving in the ocean.
The earth receives lots of ultraviolet radiation, which is damaging to light skin. On the other hand, dark skin is less able to make use of this radiation for synthesising the vitamin D that the human body needs. Studies have shown that different sets of genes give rise to dark skin in various groups of people which suggests that, as we have populated new areas of the earth we have found it necessary to adapt again and again to higher levels of sunlight. If we had not adapted the high levels of radiation would have been lethal to many of us and population in these areas would not have grown.
"sterile" means that all microbes have been killed by radiation or heat.
Doesn't it make you wonder why these radiation questions have not been answered??
