FDA称,和无线电波一样,微波是一种“非电离辐射”,这意味着微波不具有足以撞击电子使其脱离原子的能量。因此,美国癌症学会表示,并不认为微波会破坏细胞内的DNA。 In contrast, X-rays and gamma-rays are classified as “ionizing radiation”, a type that does have enough energy to remove electrons from ato...
In terms of properties, these radiations can also be defined as the radiations having both magnetic and electric fields. A few examples of electromagnetic radiation are X-rays, gamma rays, radio waves, and visible light.Answer and Explanation: ...
Ionizing radiation:includes high-energy radiation like x-rays and gamma rays. This type of radiation is commonly known to be very dangerous even in small doses. Belly Armor products do not shield against this type of radiation. The diagram below shows the Electromagnetic Spectrum. Of increasing ...
Induction of an adaptive survival response in B6C3F1 mice exposed to whole-body irradiation by low doses of X-rays (priming exposure) then to high doses of... N,Yoshida,H,... - 《Journal of Radiation Research》 被引量: 75发表: 1993年 Exposure to ionizing radiation induced persistent ge...
EFFECTS OF IONIZING RADIATION 1 Everyone on Earth is continually exposed to small, relatively harmless amounts of ionizing radiation, known as background radiation, from natural sources such as soil and rock. However, other types of ionizing radiation--x-rays, ultraviolet radiation from the sun, ...
The signature DNA lesion induced by ionizing radiation is clustered DNA damage. Gamma radiation-induced clustered DNA damage containing base lesions was investigated in plasmid DNA under cell mimetic conditions and in two cell lines, V79-4 (hamster) and HF19 (human), using bacterial endonucleases ...
Ionizing gamma rays and x-rays can cause cancer when their energy is absorbed by the tissue and chemical bonds are broken, damaging DNA. RF energy, on the other hand, produces heating of tissue. Although there is a small amount of experimental evidence that suggests RF energy can impact DNA...

Cell phones produce “non-ionizing” radiation, which, unlike X- or gamma rays, doesn’t damage DNA by stripping away electrons from molecules in cell tissue. Radiofrequency energy does, however, produce heat and, at high enough levels, can damage cell tissue. This, in the late 1990s, The...
Gamma Rays Versus X-Rays Both gamma rays andx-raysare forms of electromagnetic radiation. Their electromagnetic spectrum overlaps, so how can you tell them apart? Physicists differentiate the two types of radiation based on their source, where gamma rays originate in the nucleus from decay, while...
