英語でTECHNETIUMはどんな意味ですか？
テクネチウム
テクネチウムは原子番号43と記号Tcの化学元素です。 安定同位体を持たない最も低い原子番号要素です。 そのすべての形は放射性である。 ほぼすべてのテクネチウムは合成的に生産され、わずかな量しか天然には見出されない。 自然発生テクネチウムは、ウラン鉱石中の自発核分裂生成物として、またはモリブデン鉱石中の中性子捕獲によって生じる。 この銀色の灰色の結晶質遷移金属の化学的性質は、レニウムとマンガンの中間である。 テクネチウムの性質の多くは、元素が発見される前にDmitri Mendeleevによって予測された。 Mendeleevは彼の周期表にギャップがあり、発見されなかった要素に暫定的な名前のekamanganeseを与えた。 1937年に、テクネチウムは最初に人工的に製造された要素になり、その名が付けられました。 その短寿命γ線放出核異性体 - テクネチウム-99mは、核医学において多種多様な診断試験に使用されている。 テクネチウム-99は、ガンマ線を含まないベータ粒子源として使用される。
英語辞典でのtechnetiumの定義
辞書の中のテクネチウムの定義は、銀の灰色の金属元素であり、モリブデンの重水素による衝撃によって人工的に生成されたもので、鋼の腐食を抑制するために使用される。 半減期6時間の放射性同位体テクネチウム99mは、放射線療法に使用される。 記号：Tc; 原子番号：43; 最も安定な同位体の半減期、97Tc：2.6×106年; 原子価：0,2,4,5,6、または7。 相対密度：11.50; 融点：2204℃。 沸点：4265℃。
