Gamma radiation results from the nucleus being placed in an excited state due to some prior event, such as alpha or beta decay.
The nucleus "wants" to release its excess energy, so it does so. When it does, a photon is emitted. This is the gamma radiation. There is a comparable sequence involving the electron cloud. In that case, the resulting photon has less energy, and is characterized as an x-ray, rather than gamma.
Under normal conditions, the gamma event occurs immediately (about 1 x 10-12 seconds) after the initiating event. However, some nuclides have a meta-stable form, where the gamma event is delayed substantially after the initiating event - say for a few hours or even a day or so.
There are many examples of meta-stable isotopes. One that comes to mind is Tc-99m, which is used as a tracer in various medical scanning technologies such as a heart scan or bone scan. The advantage of this is that the body is not subjected to the stronger impact of the initiating event - just the gamma event - and that can be seen with gamma scanning instrumentation.

What product is produced when 232 90 Th undergoes alpha decay?
90Th232 undergoes alpha decay to form 88Ra228. Remember, in alpha decay, a helium nuclei is emitted, comprising two protons and two neutrons. As a result, the atomic number goes down by 2, and the atomic mass number goes down by 4.
When protactinium 229 goes through two alpha decays francium - 221 is formed?
During each alpha decay, a helium nucleus (alpha particle) is emitted, decreasing the atomic number by 2 and the mass number by 4. Protactinium-229 undergoes two alpha decays to form Francium-221. The process of alpha decay involves the emission of alpha particles from the nucleus of an atom.
Alpha decay and beta decay are two forms of decay that cause transmutation?
Transmutation, which is the change of atoms from one element to another.
What would the balanced equation for the alpha decay of thorium 229 be?
The balanced equation for the alpha decay of thorium-229, Th-229, is: Th-229 -> Ra-225 + He-4 This equation shows that a thorium-229 nucleus undergoes alpha decay to form a radium-225 nucleus and a helium-4 particle.
What is the new element formed when Pb-210 undergoes alpha decay?
An alpha particle is a helium-4 nucleus. Look up the number of the element, and subtract two from that (since helium has 2 protons). As for the number, subtract 210 - 4 (since the alpha particle has an atomic mass of 4).
When bismuth-212 undergoes alpha decay, what does it become?
When bismuth-212 undergoes alpha decay, it becomes thallium-208.
If seaborgium undergoes alpha decay which element is created?
If seaborgium undergoes alpha decay, it would create rutherfordium as the resulting element.
When an isotope undergoes alpha decay which of the following change A The name of the element B The atomic number C The mass number D All of these change?
D. All of these change. In alpha decay, an isotope emits an alpha particle, which consists of two protons and two neutrons, leading to a decrease in the atomic number and mass number of the parent isotope. This results in the formation of a new element with a different name, atomic number, and mass number.
What alpha-keto acid produce when alanine undergoes transamination?
Pyruvate
How can the element Americium change into the element neptunium?
Americium can change into neptunium through a process called alpha decay. During alpha decay, an alpha particle (helium nucleus) is emitted from the nucleus of the americium atom, resulting in the transformation of the americium atom into a neptunium atom.
What pathway would decay polonium-218 to bismuth-214?
Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.
What product is produced when 232 90 Th undergoes alpha decay?
90Th232 undergoes alpha decay to form 88Ra228. Remember, in alpha decay, a helium nuclei is emitted, comprising two protons and two neutrons. As a result, the atomic number goes down by 2, and the atomic mass number goes down by 4.
When the nuclide astatine-218 undergoes alpha decay?
When astatine-218 undergoes alpha decay, it emits a helium nucleus (alpha particle) and transforms into the new element, polonium-214. This process reduces the atomic number of the nucleus by 2 and the mass number by 4.
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
What happens when Fr-223 undergoes alpha decay?
When Fr-223 undergoes alpha decay, it emits an alpha particle consisting of two protons and two neutrons. This transforms the nucleus into a different element with atomic number decreased by 2 and atomic mass number decreased by 4.
When radon undergoes natural transmutation reaction it emits?
When radon undergoes natural transmutation, it emits alpha particles or alpha radiation. This process occurs as radon changes into a series of other radioactive elements before reaching a stable state. The alpha particles emitted during these decay processes can pose health risks if inhaled or ingested.
When uranium undergoes alpha decay it becomes an isotope of thorium. Which notation indicates the thorium isotope produced?
When uranium undergoes alpha decay, it emits an alpha particle (which is equivalent to a helium nucleus, ( ^4_2He )), resulting in a decrease of its atomic number by 2 and its mass number by 4. For example, if uranium-238 (( ^{238}{92}U )) undergoes alpha decay, it transforms into thorium-234 (( ^{234}{90}Th )). Thus, the notation for the thorium isotope produced is ( ^{234}_{90}Th ).
