A Geiger counter is a counting instrument specifically designed to detect the intensity of ionizing radiation (alpha particles, beta particles, gamma rays, and X-rays).
It uses a gas-filled tube as a probe. When voltage is applied, any radiation passing through the tube ionizes the gas, creating an electrical pulse. A connected electronic device records these pulses, measuring the radiation level over time.
The piercing shriek of the buzzer tore through the darkness, striking terror into the heart.
Shen Feng looked at the Geiger counter in his hand. The screen displayed a number: 5000.
5,000 millisieverts per hour.
'Fuck!'
The hand Shen Feng used to hold the Geiger counter trembled, and his legs felt weak.
From a health perspective, the maximum amount of radiation a person can safely absorb in a year is 1 millisievert.
