ETYMOLOGIA SŁOWA PLUTONIUM
Named after the dwarf planet Pluto because Pluto lies beyond Neptune and plutonium was discovered soon after neptunium.
CO OZNACZA SŁOWO PLUTONIUM
Pluton
Pluton to transuraniczny radioaktywny pierwiastek chemiczny o symbolu Pu i atomowej liczbie atomów 94. Jest to aktynowo metal o szaro-szarym wyglądzie, który niszcza się, gdy jest wystawiony na działanie powietrza i tworzy utlenianie. Element zawiera zwykle sześć allotropów i cztery stany utleniania. Reaguje z węglem, halogenami, azotem, krzemem i wodorem. Po wystawieniu na działanie wilgotnego powietrza tworzą tlenki i wodorki, które zwiększają objętość próbki do 70%, co z kolei spala się w postaci proszku, który może samozapłonąć się. Jest radioaktywny i może gromadzić się w kości. Te właściwości sprawiają, że obchodzenie się z plutonem jest niebezpieczne. Pluton jest najcięższym pierwiastkiem pierwotnym z powodu jego najbardziej stabilnego izotopu, plutonu-244, którego okres półtrwania około 80 milionów lat jest wystarczająco długi, aby pierwiastek znajdował się w naturze w ilościach śladowych. Pluton jest głównie produktem ubocznym reakcji jądrowych w reaktorach, gdzie niektóre neutrony uwolnione przez proces rozszczepienia przekształca jądro uranu-238 w pluton.
Definicja słowa plutonium w słowniku
Definicja plutonu w słowniku jest wysoce toksycznym metalicznym elementem transuranowym. Występuje w śladowych ilościach w rudach uranu i jest wytwarzany w reaktorze jądrowym za pomocą bombardowania neutronowego uranem-238. Najbardziej stabilny i ważny izotop, pluton-239, łatwo ulega rozszczepieniu i jest wykorzystywany jako paliwo reaktorowe w elektrowniach jądrowych i broni jądrowej. Symbol: Pu; nr atomowy: 94; okres półtrwania 239Pu: 24 360 lat; wartościowość: 3, 4, 5 lub 6; gęstość względna: 19,84; temperatura topnienia: 640 ° C; temperatura wrzenia: 3230 ° C.
CYTATY ZE SŁOWEM «PLUTONIUM»
Słynne cytaty i zdania ze słowem
plutonium.
Once we open the door to the plutonium economy, we expose ourselves to absolutely terrible, horrifying risks from these people.
There are many different kinds of radioactive waste and each has its own half-life so, just to be on the safe side and to simplify matters, I base my calculations on the worst one and that's plutonium.
For 50 years, nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium, lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task, and most of the cost, of making safe sites that have been polluted half-way to eternity.
Every actor looks all his life for a part that will combine his talents with his personality... 'The Odd Couple' was mine. That was the plutonium I needed. It all started happening after that.
My job was to produce plutonium that was used for atomic bomb.
