The dose rate (and air ionisation) due to beta and gamma radiation has been measured continuously over open grassland at Grove, Berkshire ( 51 1 2°N, 01°W), from 1961 to 1968. The measurements are compared to the dose rate calculated from the radioactivity deposited from nuclear weapon ...
磁层保护我们免受严重的辐射暴露,并偏转大多数这些辐射粒子。 由于国际空间站处于磁层内的低地球轨道,因此宇航员也可以获得相当程度的防辐射保护。 在此实验室中,学生使用盖革计数器测量环境中的辐射水平。 然后,学生将辐射暴露的个人实例(例如在飞机上飞行或接收医学 X 光检查)与宇航员接受的辐射水平进行比较。 这...

Alpha, beta, gamma rays: It almost sounds like the tagline of an old-school motion picture about aliens from outer space, newly arrived on Earth with their ultra-high-tech gadgets (and hopefully a warm disposition). In reality, this isn't too far off. Alpha, beta and gamma radiation are...
RADIOACTIVE DECAY: understand radioactive decay. describe alpha, beta and gamma radiation? Atomic Theory and Radioactive Decay Natural background radiation exists all around us. This radiation consists of high energy particles or waves being emitted from a variety of materials. Radioac...
