WHAT IS RADIATION? Radiation is the process by which energy is emitted as either particles or waves. Broadly, it can take the form of sound, heat, or light. However, most people generally use it to refer to radiation from electromagnetic waves, ranging from radio waves, though the visible ...
These particles are massive with respect to other kinds of radiation; the beta particle, for example, is some 7,000 times smaller. This on the surface might make it seem to be especially dangerous, but in fact the opposite is true: The size of the α-particles means that they penetrate ...
How is beta radiation produced by a radioactive isotope? Does beta decay change the atomic number? When an unstable isotope undergoes alpha decay, what does it give off? Is positron emission the same as beta decay? What is produced by nuclear decay?
Gamma decay: This is the release of gamma radiation from natural radioisotopes. Usually, gamma decay follows alpha or beta decay where the daughter nucleus is excited and falls to a lower energy level with the emission of a gamma radiation photon. However, gamma decay also results fromnuclear f...
Radiation is the emission of energy in waves or particles through space or matter. This can be in the form of electromagnetic radiation, such as light and radio waves, or the form of nuclear radiation. Radiation is a natural process that occurs from both natural and artificial sources...

especially cancers. We note, however, that ICRP Publication 60 mentions in the context of deterministic effects that dose rates lower than 0.1 Gy/min of low-LET radiation “result in progressively less cell killing until a dose rate of about 0.1 Gy/h or less is reached for mammalian cells”...
What is radio activity? Compare the properties of alpha, beta and gamma-rays. What is the contribution of radio activity in the development of atomic structur
What is Dark DNA? Dark DNA is the genetic code in the human genome that currently has no known original source. We have traced 8% of the human genome to viruses. 1-2% of our genome comes from other animals. Believe it or not you share 55% of your genetic code with a banana – an...
