However, much of that radiation is non-ionizing. 然而,大多的辐射是非电离的。 For the remainder that is ionizing, 余下那些电离的, our exposures are usually low, 我们暴露度基本很低, and choices like getting your home tested for radon 而且像检测你家的氡含量 and wearing sunscreen 和抹防晒霜这...
Background: Ionizing radiation is one of the environmental stresses which can be originated from the ground (radon at home) or from the space (cosmic radiation, long distance air travelling). The radiation-induced cellular effects (sister-chromatid exchanges, chromosome aberrations, apoptosis, micro...
Radon gas is not the only source of natural radioactivity. We receive about eight percent of our exposure to radiation from other radioactive elements in the earth's crust, such as thorium and potassium. Radiation levels from these sources vary in different areas of the country. ...
Radioactivity has always been present on Earth, but it was not scientifically studied until 1896. The largest source of ionizing radiation for the average American is from naturally occurring radon in the air. Without heat from naturally occurring radioactivity, the Earth’s core would have frozen ...
Radiation is a lot like heat, except you can’t feel it or see if there’s a fire. As everything around us is naturally a little bit warm, the world is also a little bit radioactive. Cosmic raysrain down from outer space 24/7. Radon gas has bubbled out of rocks for billions of...

Explores the means of eliminating indoor radon. Suggests that there is a lack of evidence of any ill effects caused by low doses of any kind of ionizing radiation.doi:10.1108/02630809110031547FremlinJ.H.MCB UP LtdStructural Survey
Why has radiation mutagenesis fallen out of favor? Why is chemotherapy administered in repeated doses or cycles? What would make stem cells useful in disease treatment? Explain why radon stands out as an important source of exposure to naturally occurring ionizing radiation. Explain human stem c...
So what then is the largest contributor of ionizing radiation? For the natural sources of ionizing radiation, actually the biggest chunk of that tends to come from radon(氡), which is a radioactive material that is present in the air. It can become a concern when it builds up in low-lyi...
Does radon go through alpha decay? Does radioactive dating use an isotope of radon? Is bremsstrahlung ionizing radiation? Do nuclear reactors let out ionizing radiation? What makes uranium-238 radioactive? How is radioactive dating measured?
