A breakthrough in heavy-element chemistry shatters long-held assumptions about transuranium elements. Researchers have ...

Vladimir Putin right now has in his sights nearly 300 pre-deployed atomic weapons set to easily launch a radioactive ...

How great was the danger from the radioactive dust that descends upon ... the drop of a “baby” atom bomb (equivalent to 5,000 to 15,000 tons of TNT) from an airplane. Since the bomb would ...

An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great ...

A hazardous waste landfill in Wayne County is preparing to take 6,000 cubic yards of soil and concrete contaminated with elevated radiation from a site in New York where the Manhattan Project ...

Alpha particles come from the nucleus of a radioactive atom. They consist of 2 protons and 2 neutrons; hence have a 2+ charge. A few centimeters of air will stop them. Alpha radiation consists of ...

An alpha particle consists of two protons and two neutrons and is often described as a helium nucleus. It is not the same as a helium atom as it does not contain any electrons but it is written ...

When a positive electron is emitted by a radioactive nucleus, it may briefly join with a negative electron to form "positronium." This simple system confirms the logic of quantum electrodynamics ...

Radioactive decay is a stochastic (i.e. random) process at the level of single atoms. According to quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long ...

Only in-vivo neutron activation analysis (IVNAA) provides non-destructive testing of total body levels of the major body elements: calcium, sodium, chlorine, phosphorus, nitrogen, hydrogen, oxygen, ...
