日本核電站危機(jī)引發(fā)人們對(duì)輻射的擔(dān)憂(yōu)

1、日本核電站危機(jī)引發(fā)人們對(duì)輻射的擔(dān)憂(yōu)The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Ma

2、ryland.日本北部受損的福島第一核電站危機(jī)引發(fā)了人們對(duì)輻射風(fēng)險(xiǎn)的擔(dān)憂(yōu)。周二，我們聯(lián)系了輻射衛(wèi)生科學(xué)專(zhuān)家喬納森·林克斯（Jonathan Links）。他是馬里蘭州約翰霍普金斯大學(xué)彭博公共衛(wèi)生學(xué)院的一名教授。Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation.林克斯教授表示，核電站工作人員是唯一處于大劑量輻射風(fēng)險(xiǎn)的人群。JONATHAN LINKS: "Of course, we don&

3、#39;t know what doses they've received, but the only persons at risk of acute radiation effects are the workers."林克斯：“當(dāng)然，我們不知道他們受到了多大劑量的輻射。但他們是唯一處于嚴(yán)重輻射影響風(fēng)險(xiǎn)中的人群。”For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind re

Then they measure how large an area is contaminated. He says if the situation is serious enough, officials co

5、uld take steps like telling people not to eat locally grown food or drink the water.林克斯教授表示，科學(xué)家可以使用電腦快速模擬什么地方會(huì)受放射性物質(zhì)影響，然后計(jì)算出受污染區(qū)域的大小。如果情況非常嚴(yán)重，官方可以采取一些措施，例如告訴人們不要食用當(dāng)?shù)胤N植的食物，不要飲用當(dāng)?shù)氐乃?。JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction,

But Professor Links says people should not worry

7、 about any radioactive material leaking into the ocean.福島的核電站反應(yīng)堆位于太平洋岸邊。但林克斯教授表示，人們不用擔(dān)心放射性物質(zhì)泄漏到海洋中。JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of dilution. So the concentration of radioactivity in the seawater would still be quite low."林克斯：“

8、即使是在情況最嚴(yán)重的事故中，海洋也能提供高度稀釋。因此海水中的放射性濃度仍將相當(dāng)?shù)??！盝apan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says.林克斯教授表示，日本是唯一遭受過(guò)原子彈打擊的國(guó)家。來(lái)自二戰(zhàn)的那種記憶可能造成日本人對(duì)輻射更加敏感。 Nex

9、t month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry.下月將是烏克蘭切爾諾貝利核電站反應(yīng)堆爆炸事故25周年。1986年發(fā)生的這次事故是全球核電行業(yè)最嚴(yán)重的一次。A new United Nations report says mor

The report says that by two thousand five the cancers had resulted in fifteen deaths.聯(lián)合國(guó)一份新的報(bào)告稱(chēng)，目前已經(jīng)發(fā)現(xiàn)超過(guò)6000例甲狀腺癌患者，他們都是在白俄羅斯，俄羅斯和烏克蘭這些受影響地區(qū)長(zhǎng)大的。報(bào)告稱(chēng)，截至2005年甲狀腺癌已導(dǎo)致15人死亡。The cancers were largely ca
