No time required for completion of first half life is not same as 2nd one.Even it has been found that time required for 99.9% completion is almost 10 times of half life period.

Which of the following particles has the same mass as an electron but a positive charge and is sometimes emitted from the nucleus during radioactive decay?
A positron.
How and where are gamma rays produced?
Gamma rays are particularly energetic photons. On Earth, they are emitted from radioactive substances, during radioactive decay and are also created in x-Ray machines. They can also be produced during very energetic events in space, such as the explosion of a star. Cosmic Rays are gamma rays that continually bombard the Earth.
A beta particle may be spontaneously emitted from?
Positrons are emitted from proton-rich radioactive during positive beta-decay.
Why iodine tablet supplied to people living near nuclear power plant?
Iodine tablets are used in a nuclear accident to saturate the thyroid with non radioactive iodine. During a nuclear accident, radioactive iodine is released and the critical organ in the human body is the thyroid gland. Therefore if the thyroid is already full of non radioactive iodine the radioactive iodine can not be absorbed.
How does radioactive materials used to produce nuclear energy?
Nuclear energy is produced by fission of new fuel, which is only very slightly radioactive to start with (it is safe to handle unprotected). It becomes radioactive during the reactor's operation, and at the end of life the radioactivity of the fuel contributes some 5% or so of the output heat, the rest is due to fission directly. There are some uses for radioactive isotopes to produce electricity directly but these are only used in satellites for small instrument type supplies.
When radioactive decay occurs a atom is always produced by the action?
During any type of radioactive decay, one isotope (type of atom) will convert into a different isotope.
What are unwanted radioactive products formed during nuclear reactions called?
Radioactive waste.
What is lost during radioactive decay?
Decay energy is the energy that has been freed during radioactive decay. When radioactive decay is ongoing it drops off some energy by means of discharging radiation.
What is the percentage of radioactive nuclei left after 3 half lives have passed?
12.5%
Are x-rays emitted during radioactive decay?
Yes they are. Nearly all kinds of electromagnetic radiation are emitted during radioactive decay
How can water become radioactive?
Yes they all are A small percentage of each element in all existence is radioactive and some elements are nearly 100% radioactive if not exactly 100% radioactive, so encountering radioactivity in air, soil, and water is inevitable.
What are the nuclear changes during decay of copper 67?
Copper-67 undergoes beta decay with a halflife of 59 hours, becoming stable Zinc-67.
What is necessary for you to be able to explain what happens during radioactive decay?
To fully explain radioactive decay you need quantum mechanics.
A negative charged particle emitted during radioactive decay?
An electron during beta decay.
Gamma rays are emitted by?
they are emitted by radioactivity during radioactive decay.
What was russia like during the middle ages?
Not a Radioactive snowy wasteland
Gamma rays are emitted by what?
they are emitted by radioactivity during radioactive decay.
