ionizing radiation dose 中文意思是什麼
ionizing radiation dose
解釋
電離輻射量-
In the laboratory experiment part, human peripheral blood, cultured cells and icr mice were study objects. the changes of mitotic chromosome numbers were measured by human metaphase chromosome counts and statistic analyzed used x2 - test. the changes of meiotic chromosome numbers were measured by mice one - cell zygote chromosome counts and statistic analyzed usedx2 - test. the effects of low dose ionizing radiation on the expression of topoisomerase ii were measured by immunocytochemistry, western blot and rt - pcr
流行病學結果顯示長期小劑量輻射接觸與染色體不分離呈正相關，為進一步在細胞遺傳學和分子生物學方面研究小劑量電離輻射與染色體不分離關系及其機制，本課題第二部分以外周血、培養細胞、 icr小鼠為研究對象，用外周血染色體計數和單細胞受精卵染色體計數的方法研究小劑量輻射和拓撲異構酶復旦大學2000級博士生學位論文11a抑制劑及其二者的協同效應對有絲分裂和減數分裂染色體不分離的影響，用免疫細胞化學染色、 westernblot 、 rt pcr等方法研究了電離輻射引起拓撲異構酶a表達變化。 -
The expression of topoisomerase ii of cultured cells treated low dose ionizing radiation decreased and then returned as time went. and become outstanding as radiation dose and frequency were added. inhibitor of topoisomerase ii could cause chromosome non - dis juction in mitosis and meiosis. and the co - effect of inhibitor of topoisomerase ii and ion
05 ） ，具有隨照射次數增加而增加的趨勢；小劑量電離輻射可以引起拓撲異構酶a表達變化，隨照射后時間延長先下降后回升，隨照射劑量和次數的增加，變化更加明顯；拓撲異構酶11a抑制劑可引起有絲分裂和減數分裂時染色體的不分離；拓撲異構酶a抑制劑和電高輻射的協同作用使染色體不分離更加明顯。 -
This research has closed relationship with a wide range of cross - science areas, such as basic research on cancer therapy by heavy ion radiation method, radiation danger level evaluation in space and biological damage induced by long term, low - level dose radiation environment, etc. dna is the carrier of biological information and the main target of biological effects induced by ionizing radiations
從重離子治癌的基礎性和先導性的研究，載人航天飛行過程中的太空輻射危險性評估，到長期在低劑量輻照環境下的放射性對機體損傷等等，都與電離輻射所致生物損傷的研究有著密切的關系。 dna （脫氧核糖核酸）是生命信息的載體，也是輻射生物效應的最主要的靶分子。 -
Article 5 in order to limit the radiation exposure from radiation sources or practices, the competent authority shall refer to the latest standards of the international commission on radiological protection to lay down the safety standards for protection against ionizing radiation, and if warranted, to formulate the relevant guides so as to regulate the levels of radiation protection practice and personal dose limits
第5條為限制輻射源或輻射作業之輻射曝露，主管機關應參考國際放射防護委員會最新標準訂定游離輻射防護安全標準，並應視實際需要訂定相關導則，規?輻射防護作業基準及人員劑量限度等游離輻射防護事項。 -
" equivalent dose " and " effective dose " are used for assessment of the risk of biological effects produced by ionizing radiation
當量劑量及有效劑量是評價產生生物效應的危險時常用的劑量學量。 -
On human bodies. " equivalent dose " and " effective dose " are used for assessment of the risk of biological effects produced by ionizing radiation
當量劑量及有效劑量是評價產生生物效應的危險時常用的劑量學量。 -
05 ), and had the tendency of increase as radiation frequency increased. the effect of low dose ionizing radiation on meiosis chromosome non - disjunction was remarkable from 2 gy ( p < 0
05 ） ，且具有隨照射次數的增加染色體不分離增加的趨勢；小劑量電離輻射對減數分裂的影響是從zgy開始，染色體不分離較對照增加（屍0
