Sentences with phrase «for radioactive particle»
And that means there may be two direct paths for radioactive particle byproducts of nuclear fission, such as cesium 137 and iodine 131, to escape and spread radiation — cracks in containment as well as the spent fuel pools now open to the air.

The International Monitoring System (IMS), established by the Comprehensive Nuclear - Test - Ban Treaty, has a number of different ears to the ground to detect clandestine nuclear weapons testing: seismic networks that listen for terrestrial shock waves, hydroacoustic networks that scan the oceans for sound waves, and radionuclide networks to sniff out radioactive particles that nuclear explosions produce.
