What is Radioactivity? The term radioactivity is used in reference to express the behavior or property of some specific material matter that exhibits spontaneous emission of energy or subatomic particles. It is sometimes called radioactive decay. One should note here that any molecule that has an unstable nucleus will decompose into one or more stable […]


What are Particulates? Particulates, commonly known as Particulate Matter are basically small-sized particles that are present in the air. These particles can be present naturally in air or sometimes these are the result of man-made or anthropogenic activities. The particulates can either exist in the form of small solid particles or liquid droplets. There is […]
