[933] Tattoo

Title Text:I calculate that the electrons in radiation therapy hit you at 99.8% of the speed of light, and the beam used in a 90-second gamma ray therapy session could, if fired with less precision, kill a horse (they did not let me test this).

我做過計算,放射治療用的光速 99.8% 的電子,以及伽瑪治療用的 90 秒伽瑪射線,如果用比較低的精準度發射,可以殺死一匹馬(他們不讓我實際測試)。
