How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
the halflife is 10 days
What happens to the density of a given substance if you increase the amount of substance that you have?
No change: Density is a property of the substance (physical property), which is not changed by the amount of substance.
What does not affect the half-life or a radioactive substance?
The temperature The total amount of the substance The addition of a catalyst ~
What is the activity of a radioactive substance?
any one or a combination of radioactive substances that gives off photons that are usually considered harmful to humans and other life forms
When the radioactive isotope of Th-234 emits a beta particle to become Pa-234 it also loses a small amount of mass which is emitted as?
gamma radiation!
Is there any way to change the average amount of radiation emitted from a radioactive substance?
No, there is none at all. Shielding can be placed around it to limit exposure, but it has no effect on what the substance is emitting.
Does the amount of radiation you give off depend on what is inside of you?
Yes. Radiation is emanated from radioactive material, so the amount of radiation that someone "gives off" is a function of how much radioactive material they have inside them.
WHAT DOES The amount of radiation that an individual absorbs depends on?
Time exposed to a radioactive source and the Distance a person is from a radioactive source and Type and amount of shielding between a person and a radioactive source.
The amount of radiation that an individual absorbs depended on what?
Time exposed to a radioactive source Distance a person is from a radioactive source Type and amount of shielding between a person and a radioactive source X All answers are correct

When the amount of a radioactive substance is reduced by 50 percent what has occurred?
Half-Life APEX (; xoxo
Can radiation from americium kill people?
Americium being very radioactive this is possible; but this depends on the time of exposition to radiation, amount of americium, shielding of the source etc.
What happens to a radioactive person?
Although all people do contain a small amount of radioactive isotopes in their bodes, making them slightly radioactive, it is not nearly a large enough dose to have any noticeable effects. But if you mean a person who is highly radioactive, then the most likely way for that to happen is if a radioactive substance were to enter that person's body. The effects of that would depend on the dose and the substance. For instance, plutonium, which emits alpha, beta and gamma rays causes radiation sickness and an increased chance of cancer. And radium which emits more alpha rays then beta or gamma rays and is much more radioactive then plutonium causing much the same effects and decays into radium. As radium is chemically similar to calcium, it can cause great harm by replacing calcium in the persons bones.
What happens when a metal is exposed to radiation?
Yes, if the "radioactive waves" are particulate radiation. Electromagnetic radiation (X-rays or gamma rays) are ionizing radiation, but they will not make something radioactive. Particulate radiation can do that; it can activate a substance. The nature of the resulting radioactive material will depend on what kind of particulate radiation a substance is exposed to, and what kind of substance is being exposed to the radiation. To cite an example, if we lower a "slug" of cobalt-59 into an operating nuclear reactor to bathe it in the neutron flux, the cobalt-59 will absorb a neutron and become cobalt-60. Cobalt-60 is a gamma ray emitter, and a strong one. We can withdraw our slug and put it in a "vault" or "casket" to shield us from the radiation, and then use this as a radiation source to perform X-ray analysis of welds in something like piping. We open a "door" on the package by remote control, of course. By having a portable source, we can avoid having to drag an X-ray machine somewhere and try to find a place to plug it in. We can also install a big source in an industrial setting to irradiate and sterilize something like band-aids. This first aid product is manufactured and packaged and then exposed to a big shot of radiation to "clean" it. And it works.
What does not affect the half-life or a radioactive substance?
The temperature The total amount of the substance The addition of a catalyst ~
The radioactive substance Carbon-14 has a half life of 5730 years. After 1000 years there is 2.66 grams remaining. What was the initial amount of the substance?
3.002 grams, approx.
