The reactor is only one of four in the world that produce medical radioactive isotopes.

该反应堆是世界上仅有的四个生产医用放射性同位素的反应堆之一。

Lead has four stable isotopes: Lead 204, 206, 207, 208, but there are more than 20 kinds of radioisotopes.

铅在自然界中有4种稳定同位素：铅204、206、207、208，还有20多种放射性同位素。

Low rotten bituminous coal (jet coal, it glues coal to be and weak to glue coal), natural radioactive level lower,( 238U: 33.2- 50.0Bq/kg , 232Th: 52.5- 54.4Bq/kg , 226Ra: 30.6- 56.5Bq/kg ), obviously lower than the brown coal than activity, and the uranium , radium which the companion grew is in a basic balance, uranium , thorium are also in a basic balance.

低变质烟煤（包括长焰煤、不粘煤和弱粘煤）天然放射性水平较低，（238U：33.2～50.0Bq/kg、232Th：52.5～54.4Bq/kg、226Ra：30.6～56.5Bq/kg），比活度明显低于褐煤，且伴生的铀、镭基本平衡，铀、钍亦基本平衡。

To wags during the cold war, ground zero was a favoured spot: better to be incinerated in the first mushroom cloud, they joshed, than to wake up to a world of radioactive rubble.

对于冷战期间诙谐幽默的人来说更愿意选择地面零点：他们冷嘲到，在第一个蘑菇云出现时就被烧死总比过后意识到全世界到处都有放射性物质要好。

There has been a great deal of speculation over the zerg choice to occupy Char, given its harsh environment and total lack of any organic life forms to exploit. Theorists are evenly split among the ideas that Char forms a useful jump-off point to the core worlds of terran and protoss space, that its inhospitable nature makes it easier for the zerg to defend it, or that Char\'s high radiation levels promote an increased rate of mutation in zerg organisms to enable forced evolution of specialist strains.

在虫族占据 Char 期间有大量的投机活动，鉴于有害的环境和缺乏有机生命形势的利用，理论家们用均匀分裂的方法在 Char 形成了一个可用的进入人类世界和神族空间的跳跃点， Char 荒凉的自然性质更利于虫族的防守，甚至 Char 的高度放射性等级促进了虫族机体组织的变异使其演变出特殊的种类。

The technique of Radome of Interesting was used in knee and whole bone, and R value was calculated.
