Most gold is made up of isotopes that have never been observed to undergo radioactive decay and therefore has no known half-life. Some synthetically prepared isotopes of gold may be radioactive and thus have a half-life, the length of which would depend on the particular isotope.

Why is americium used in gauges?
Americium 241 is an artificial isotope with a long half life - 432,2 years - and a gamma ray emitter. Being a strong gamma emitter it can be used for gamma radiography of materials and for thickness gauges.
Can you identify atoms that will undergo radioactive decay in half -life period?
Yes and no. Each radioisotope has a distinct half-life so, if you can measure the half-life, you can probably identify the isotope. The problem is that most isotopes decay to other isotopes that are also radioactive, and they have their own half-life, so you must differentiate which isotope you are looking at when you count its decay events in a detector. If the decay event is a gamma event, it is relatively straightforward to differentiate, but if it is beta, it is difficult, though not impossible, because the output energy is a spectrum, and not a single photopeak.
What is an isotope that the time it takes it to decay to half its original mass?
c.half-life
What is the half life of promethium?
Promethium 145 has a half life of 17.7 years. Promethium 146 has a half life of 5.53 years. Promethium 147 has a half life of o.22 years.
Who describes an isotopes half life?
Half-life is described in time units.
Does gamma rays per second effect physical half-life?
Gamma rays or gamma radiation will cause severe internal damage as well and skin burns. Even at half-life the gamma ray can cause damage to who ever come in contact with the ray.

What are the release dates for The Facts of Life - 1979 Gamma Gamma or Bust 5-3?
The Facts of Life - 1979 Gamma Gamma or Bust 5-3 was released on: USA: 28 September 1983
Explain why is americium-247 ideal to use in gauges and distance sensing devices?
Americium 241 (not Am 247 ) is an artificial isotope with a long half life - 432,2 years - and a gamma ray emitter. Being a strong gamma emitter it can be used for gamma radiography of materials and for thickness gauges.
If chromium undergoes gamma decay what does it become?
It would become vandium, iron, titanium or maganese depending on the amount of decay and the half-life of chromium
How do gamma rays affect a daily life?
one way is that gamma rays can get rid of cancer cells
What is the physicist's response to the creationist claim that polonium 218 in granite is evidence of creation?
This is how Polonium 218 gets here: It is constantly being formed. The Universe is Billions of years old. If there is a God then he is much greater than "Creationists" could ever imagine.Start with a uranium-238 atom. This atom has 92 protons and 146 neutrons. It has a half-life of 4.5 billion years. When it decays it emits an alpha particle, leaving behind a thorium-234 atom.A thorium-234 atom has 90 protons and 144 neutrons. It has a half-life of 24.5 days. When it decays it emits a beta particle and a gamma ray, leaving behind a protactinium-234 atom.A protactinium-234 atom has 91 protons and 143 neutrons. It has a half-life of 269,000 years. When it decays it emits a beta particle and a gamma ray, leaving behind a thorium-230 atom.A thorium-230 atom has 90 protons and 140 neutrons. It has a half-life of 83,000 years. When it decays it emits an alpha particle and a gamma ray, leaving behind a radium-226 atom.A radium-226 atom has 88 protons and 138 neutrons. It has a half-life of 1,590 years. When it decays it emits an alpha particle and a gamma ray, leaving behind a radon-222 atomradon-222, with a half-life of 3.825 days, emits an alpha particle to become polonium-218.polonium-218, with a half-life of 3.05 minutes, emits an alpha particle to become lead-214.lead-214, with a half-life of 26.8 minutes, emits a beta particle and a gamma ray to become bismuth-214.bismuth-214, with a half-life of 19.7 minutes, emits either an alpha particle or a beta particle and a gamma ray to become either thallium-210 or polonium-214.polonium-214, with a half-life of a 150 microseconds, emits an alpha particle to become thallium-210.thallium-210, with a half-life of 1.32 minutes, emits a beta particle to become lead-210.lead-210, with a half-life of 22 years, emits a beta particle and a gamma ray to become bismuth-210.bismuth-210, with a half-life of five days, emits a beta particle to become polonium-210.polonium-210, with a half-life of 138 days, emits an alpha particle and a gamma ray to become lead-206.lead-206 is a stable isotope of lead.Answer: The experiment performed by the creationist Robert Gentry about the existence of polonium halos found in granite yielded inconclusive results. Robert Gentry does not have any evidence that the halos are indeed a result of polonium isotopes decaying.
An isotope that's element is used in nuclear shields?
Depleted uranium, which is mostly Uranium-238 is used for shielding gamma radiation. Though it is radioactive, it has a very long half life, and is very effective against gamma radiation. The result is that it makes a pretty good shield.
How are gamma rays used in your everyday life?
While we are all exposed to them a little form rocks and from outer space, they are NOT used in everyday life. Gamma rays are dangerous.

Can gamma rays be stopped and how?
It seems that any matter will stop part of the gamma rays; to stop most of the gamma rays from passing, you would need a fairly thick layer of matter. The thickness required to block half of the gamma rays depends on the energy of the gamma rays. Just about any matter will do. For more details, check the Wikipedia article "Gamma ray", section "Shielding".
