Matter is composed of atoms. Some atoms are unstable. As these atoms change to become more stable, they give off invisible energy waves or particles called radiation. There are different types of radiation, some more energetic than others. One type of radiation, non-ionizing radiation, has enou...
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...
Up to 10% of total cancer cases may be induced by radiation (64), both ionizing and nonionizing, typically from radioactive substances and ultraviolet (UV), pulsed electromagnetic fields. Cancers induced by radiation include some types of leukemia, lymphoma, thyroid cancers, skin cancers, sarcomas...
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...

sparing techniques were developed to reduce the exposure of the heart to ionizing radiation and are currently used in daily clinical routine. The purpose of this review is to summarize the current knowledge about radiation-induced cardiotoxicity, to discuss the previously cardiac dose constraints, and...
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 cell research and treatment. Explain how radiation can...

The radon-derived ionizing radiation and some components of cigarette smoke induce oxidative stress by generating reactive oxygen species (ROS). Respiratory lung cells are subject to the ROS that causes DNA breaks, which subsequently bring about DNA mutagenesis and are intimately linked with ...
In accordance with the results that cisplatin via stimulation of ATM activity can abrogate its radiosensitizing effect, ATM deficient cells were significantly sensitized to ionizing radiation by cisplatin. The results obtained indicate that ATM targeting can potentiate cisplatin-induced radiosensitization. ...
