BBC原文：

The first human trial of a new type of pill, designed to remove harmful radioactive contamination from the body, is starting in the US. The drug, HOPO 14-1, is thought to work against several materials that might be used in weapons, including uranium. If it proves safe and effective it could guard against potential harm from nuclear accidents or terrorist attacks.

一种旨在清除人体有害放射性污染的新型药片将首次在美国开始进行人体试验。这种名为HOPO 14-1的药物被认为可以对抗几种可能用于武器的材料，比如铀。如果它被证明是安全有效的，它可以防止核事故或恐怖袭击的潜在危害。

About 42 volunteers will try different doses, checking for side effects.

There will be "intensive safety monitoring", with results from the phase one study expected in 2024, say the trial leaders from SRI International of Menlo Park, California, who are receiving funding from US government agency the National Institutes of Health.

大约42名志愿者将尝试不同的剂量，以检查该药物的副作用。加州门洛帕克的SRI国际研究所的试验负责人表示，将进行“密集的安全监测”，预计将于2024年得出第一阶段研究的结果。该研究所正在接受美国政府机构美国国立卫生研究院的资助。

7.side effect 副作用

8.dirty bomb 放射性炸弹

例句：Also known as a radiological dispersal device, a dirty bomb is an explosive that has been mixed with radioactive material so that when it goes off there will be contamination of the blast zone.

脏弹也被称为放射扩散装置，是一种与放射性物质混合的爆炸物，因此当它爆炸时，爆炸区域会受到污染。
