【多选题】下列不属于电离辐射的是Which of the following is notionizing radiation?A. 电脑产生的辐射 Radiation
[translate] aThe energy density per atomic transition of ionizing radiation is very high; it can break apart molecules and induce ionization, which is not achieved by mere heating. 能量密度每致电离辐射的原子转折非常高; 它可能分开分子和导致电离,没有由仅仅热化达到。 [translate] ...
The method is characterized in that, after commonly breeding larvas and feeding them with mulberry up to their fourth moulting, the caterpillars are taken between the seventh and the ninth day consecutive to said fourth moulting in order to be treated in a succession of operations comprising the...
intense erposure to radiation from cellphones with an increased risk of cancer in the heart orbrain."可知,现在一项在老鼠身上进行的新研 究增加了那些忧虑,故划线词与addsto意义相 近。 2.根据第二段中的“T hey could lead to studies r esearching how cellphone radiation might cause cancer,he says...
Background: Ionizing radiation is one of the environmental stresses which can be originated from the ground (radon at home) or from the space (cosmic radia... Background: Ionizing radiation is one of the environmental stresses which can be originated from the ground (radon at home) or from ...
根据第三段的“non- ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation..."可知,本段主要讲的是手机辐射的特点,它是非电 离的,其危害性远低于电离辐射。 4.B 解析:...
发明人: 馬場 茂雄 摘要: PURPOSE: To measure distribution of real radioactive nuclide of each part of a sample by measuring density of the sample and an ionizing radioactive quantity, and correcting them by a self absorption rate corresponding to the density.收藏...
aCMC hydrogel formation induced by ionizing radiation is achievable only at certain conditions, i.e. at high concentration of the polymer in aqueous solution, which despite of repulsive ionic forces facilitates bimolecular reactions. CMC致电离辐射导致的水凝胶形成是仅可达成的在某些情况,即。 以聚合物...
Intake of high doses of chemical mutagens or exposing to ionizing radiation may also cause mutation to occur. So, Frameshift mutation gives most damage to the cells or organisms. Insertion or deletion of sequence of nucleotides which leads to frameshift mutation is more damaging. It causes chang...
