It uses a gas-filled tube with a high-voltage central cable to collect ionization caused by incident radiation. It can detect alpha, beta, and gamma radiation, although it cannot distinguish between them. A nuclear radiation detector is a device that measures radiation levels for early warning and general monitoring systems in REM. The display shows both the current level in REM and the total exposure in REM hours.

Can you detect a nuclear weapon?
In the absence of armor, ordinary nuclear weapons containing quantities in kilograms of ordinary weapons-grade plutonium or uranium 238 (6 percent plutonium-240) can be detected by neutron or gamma counters at a distance of tens of meters. There are many different ways to detect a nuclear detonation, including seismic, hydroacoustic and infrasound detection, air sampling, and satellites.
Does nuclear testing still occur?
Since the first nuclear test explosion on July 16, 1945, at least eight nations have detonated 2,056 nuclear test explosions at dozens of test sites, including Lop Nor in China, the Pacific Atolls, Nevada, Algeria, where France carried out its first nuclear device, Western Australia, where the United Kingdom, K. Exploited nuclear weapons, the South Atlantic, Semipalatinsk in Kazakhstan, throughout Russia and elsewhere.
Are underground nuclear tests safe?
The effects of an underground nuclear test can vary depending on factors such as the depth and performance of the explosion, as well as the nature of the surrounding rock. If the test is carried out at a sufficient depth, the test is said to be contained, without venting gases or other contaminants to the environment.
Why nuclear is dangerous?
A major environmental concern related to nuclear energy is the creation of radioactive waste such as tailings from uranium mills, spent (used) reactor fuel, and others. At high doses, ionizing radiation can cause immediate harm to a person's body, including, at very high doses, radiation sickness and death.
