Electricity is all around us all the time.​

電磁輻射無時無刻圍繞著我們​

電磁輻射無時無刻圍繞著我們​​

It makes our lives easier, safer, more fun,​

它讓我們的生活更輕鬆、安全、有趣​

我們大多數人從未想過它是否會帶來負面影響​

But is there such a thing as too much electricity?​

我們知道電磁輻射是現代世界的基礎​​

我們知道電磁輻射是現代世界的基礎​​​

Could the thing that is the foundation of the modern world​

但太多的電磁輻射圍繞在我們身邊

let's try to understand what electricity is,​

先來了解電磁輻射到底是什麼​

先來了解電磁輻射到底是什麼​​

Electricity is the movement of an electric charge.​

This movement generates ​​Electric​ and ​Magnetic Fields​

that spread out through space and carry energy.​

We call this phenomenon:​ ​​​Electromagnetic Radiation​.​

Radiation is a word that makes people very nervous.​

輻射這個詞聽起來十分可怕​​

But, to radiate just means, "giving off".​

Like when the radiator in your house gives off heat​

Different parts of the electromagnetic spectrum​

correspond to different types of radiation.​

And, many of them are perfectly harmless.​

are strong enough to rip electrons out of their atoms,​

強度足以將電子從原子中撕裂出來​

which can cause burns and genetic damage.​

This is what many people have in mind when they hear the term "radiation".​

這就是為什麼人們懼怕「輻射」這個詞​

The rest of the spectrum covers a large range of longer waves​

其餘頻譜涵蓋了大範圍的長波​

從可視光、紅外線、微波到無線電波​

這就是從各種人類技術發出的輻射​

This is the kind of radiation that's emitted by all sorts of human technology.​

electric power lines, and household appliances.​

這種輻射不會破壞我們體內的分子​

This radiation doesn't disrupt molecules in our body.​

然而，某些輻射可以刺激肌肉和神經​

然而，某些輻射可以刺激肌肉和神經

However, some kinds of radiation can stimulate muscles and nerves​

並且還可以使你的頭髮振動​​

and can also make the hair on your body vibrate,​

which can sometimes cause a tingly feeling above certain threshold values.​

不過其他種類的輻射對於製作晚餐很有用

不過其他種類的輻射對於製作晚餐很有用​

Other kinds are useful for making dinner.​

微波爐電磁場使水分子轉動摩擦因而產生熱​

微波爐電磁場使水分子轉動摩擦因而產生熱​​

Microwaves push the water molecules in your food around​

例如：您在海灘享受溫暖的​陽光

例如：您在海灘享受溫暖的​陽光​

是因為你的皮膚暴露在來自太陽的太陽輻射而升溫

是因為你的皮膚暴露在來自太陽的太陽輻射而升溫​

For example, the pleasant warmth you feel at the beach​

我們被通常無害的天然輻射圍繞​

我們被通常無害的天然輻射圍繞​​

is your skin heating up from exposure to​

electromagnetic infrared radiation from the sun.​

We are surrounded by natural, and generally harmless,​

環境中的電磁輻射日益增加​​

sources of electromagnetic radiation all the time​

在 1979 年的一項研究首次引起公眾的注意​

發現白血病與住家附近的輸電系統之間存在相關性​

發現白血病與住家附近的輸電系統之間存在相關性​​

we have added a lot of it to our immediate environment.​

儘管如此，這項研究很快就失去了信譽

儘管如此，這項研究很快就失去了信譽​

The question of whether this is actually dangerous​

first got public attention when a 1979 study​

而且無法證實這其中的關聯​​
