Nuclear weapons tests are tests implemented to determine the effectiveness, yield and explosive capability of nuclear weapons. Tungsten alloy radiaiton shielding for nuclear weapons testing can yield information about how the weapons work, along with how the weapons behave under a variety of conditions and how personnel, structures and equipment behave when subjected to nuclear explosions. Nuclear testing has often been used as an indicator of scientific and military power, and many tests have been openly political in their intention; most nuclear weapons states publicly declared their nuclear status by means of a nuclear test.

Nuclear weapons tests have been divided into atmospheric testing，underground testing，exoatmospheric testing and underwater testing. The 2000 Report of the UNSCEAR to the General Assembly states that, the main man-made contribution to the exposure of the world's population to radiation has come from the nuclear weapons testing in the atmosphere, from 1945 to 1980. Each nuclear test resulted in unrestrained release into the environment of a large number of radioactive materials, which were widely dispersed in the atmosphere and deposited everywhere on the Earth's surface. The emergence of radiation in nuclear testing is inevitable, so the shielding performance of radiaiton shielding for nuclear weapons testing is very important.

Tungsten alloy radiaiton shielding for nuclear weapons testing played the great shielding performance of tungsten alloy perfectly. Due to its high density, it can achieve great shielding effects, which make it shield radiation in a high degree.
