What is radioactive alpha beta and gamma radiation?

Alpha denotes the largest particle, and it penetrates the least. Alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral. Beta particles are high energy electrons. Gamma rays are waves of electromagnetic energy, or photons.

What are the 2 types of radiation?

There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.

What is the difference between alpha and beta radiation?

Alpha radiation is the name for the emission of an alpha particle in fact an helium nuclei, beta radiation is the emission of electrons or positrons, and gamma radiation is the term used for the emission of energetic photons. When uranium salts were found in 1896 to produce unknown emissions, two types of radiation, X-rays and cathode rays,

What causes the emission of alpha beta gamma rays?

The emission of gamma very often accompany the transformations of nuclei. IN2P3 Alpha, beta and gamma decay are a result of the three fundamental forces working in the nucleus – the ‘strong’force, the ‘weak’force and the ‘electromagnetic’force.

What kind of instruments are used to detect gamma radiation?

Gamma radiation is detected with survey instruments, including civil defense instruments. Low levels can be measured with a standard Geiger counter. Gamma radiation or X-rays frequently accompany the emission of alpha and beta radiation. Instruments designed solely for alpha detection will not detect gamma radiation.

When did Ernest Rutherford discover Alpha Beta Gamma?

It took four more years to isolate polonium and radium from the ore to study their chemical properties. Ernest Rutherford discovered three types of emissions from radioactive substances as he experimented with them between 1900 and 1903. He named them alpha, beta, and gamma radiation. They differ in their ability to penetrate matter.
