Uncertainties, which taint the risk estimations, assume a particular importance because they are at the origin of the request for expert and value judgments and represent the critical point of the discussions on the ionizing radiation risks. Our study allows us to look further into the problem of...
Radioactive materials that decay naturally produce ionizing radiation, which has the capacity to cause serious damage to the body's internal chemistry, breaking the chemical bonds between the atoms and molecules that make up our tissues. The body responds by trying to repair this damage, but somet...
An interest- ing issue is the fact that effects of radiation are not limited to irradiated cells but is also communicated to adjacent cells, a phenomenon known as the radiation-induced bystander effect (RIBE) (157, 169, 170). Observed RIBEs are either beneficial (sen...
Which of the following is ionizing radiation?( ) A、电脑产生的辐射 Radiation generated by computers B、吹风机产生的辐射 Radiation generated by hair dryers C、DR产生的辐射 Radiation generated by DR D、微波炉产生的辐射 Radiation generated by microwave ovens ...
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...
Double-stranded DNA breaks arise from ionizing radiation, reactive oxygen species, replication errors, and inadvertent cleavage by nuclear enzymes and by exogenous chemicals. These breaks can create diverse DNA end structures that must be repaired. We have developed a NHEJ reconstitution assay that can...
Which type of electromagnetic radiation has the shortest wavelength? What are the different types of infrared waves? A certain substance strongly absorbs infrared light having a wavelength of 6.50m. What is the frequency in hertz of this light? Are infrared rays ionizing radiation? What is the ...
Which of the following types of radiation has the lowest penetrating power? a. Gamma ray. b. Alpha particle. c. Beta particle (electron). Penetrating Power: The capability of a particle to enter from one medium to another with a more...
Types of Radiation Ionizing radiation, which can damage the cells in your body, is more dangerous than non-ionizing. There are a few types of radiation, and each affects people differently. Your iPhone uses radio and microwave energy to help you make phone calls and connect to the Internet....
(2016) demonstrated that the expression of GDF15 was sig- nificantly increased in human aortic endothelial cells (HAEC) made senescent by ionizing radiation. They reported that many biomarkers of cellular senes- cence could be reversed by the knockdown of GDF15 expression. Park et al. (...
