alpha radiation

常見例句

Radon gas escapes easily from the ground into the air and emits heavily ionizing radiation called alpha particles.
氡氣很容易從地下釋放到空氣中并發(fā)射出稱為阿爾法粒子的強(qiáng)致電離輻射。
If radioactive material is ingested or inhaled into the body, however, it is actually the lower energy alpha and beta radiation that becomes the more dangerous.
然而，如果人體攝取或吸入放射性材料，低能的α和β粒子更為危險。

About 10 to 15 years later, another physicist, Ernest Rutherford, actually put this plum pudding model to test, Ernest Rutherford and he did it through studies that he'd been doing on radiation that was emitting something called alpha particles.
因此我們要，在上面再做改進(jìn),大概過了10到15年，另外一個物理學(xué)家,用實驗來檢測這個李子布丁模型,他一直從事alpha粒子輻射研究。

The Alpha Magnetic Spectrometer was designed to search for dark matter by collecting high energy radiation known as cosmic rays, and then sort through it looking for a certain class of particle believed to be created after two bits of dark matter collide in space and destroy each other.
