It varies, depending on the particular radionuclide involved. The half-life of Carbon-14, for instance, is 5730 years, while Iodine-131 is 8 days, Cesium-137 is 30 years, and Uranium-235 is 700 million years. For more information, please see the Related Link below.

What are three physical factors that have no effect on the amount of radiation emitted by a radioactive source?

The half-life of the radioactive material, the type of decay process, and the initial quantity of radioactive material are physical factors that do not affect the amount of radiation emitted by a radioactive source. Radiation emission is solely determined by the intrinsic properties of the radioactive material itself.


The rate of decay of a radioactive element is measured by its what?

The rate of decay of a radioactive element is measured by its half-life, which is the time it takes for half of a sample of the element to decay. This measurement is used to determine the stability or instability of the element and to predict its rate of decay over time.


How many radiation do radioactive material emit?

Radioactive materials emit particles or energy in the form of radiation. The amount of radiation emitted by a radioactive material depends on its specific properties and decay process. Radiation is typically measured in units such as becquerels (Bq) or curies (Ci), which indicate the rate of radioactive decay.


Each of the objects below has a different amounts remaining of the original radioactive material X. Which object is most likely the oldest?

The object with the smallest amount of original radioactive material X remaining is most likely the oldest. Over time, radioactive material decays at a consistent rate, so the object with the least remaining material has been decaying the longest.


Why a changed electroscope will discharge when placed near a radioactive material?

A changed electroscope will discharge near a radioactive material because the radioactive material emits ionizing radiation (such as alpha and beta particles) that can ionize air molecules around the electroscope. This ionization causes the charge on the electroscope to leak away, resulting in discharge.

Can radioactive be recycled?

Yes, there are a number of uses for radioactive material. It depends on the type of radioactive material.


What is defreent between radioactve and nuclear material?

Radioactive material refers to substances that emit radiation spontaneously, while nuclear material is any material that can undergo nuclear reactions such as fission or fusion. Essentially, all radioactive material is nuclear material, but not all nuclear material is necessarily radioactive.


What is the name for the emission of rays and particles by a radioactive material?

The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.


What can be naturally radioactive?

The core of the earth is radioactive, as is the sun. Granites, which crystallize from mantle material are commonly slightly radioactive.

What type an amount of radioactive material is found in the M43A1 detector?

The M43A1 detector contains a small amount of radioactive material typically in the form of a sealed radioactive source, such as cesium-137 or americium-241. This radioactive material is used to generate radiation for detection purposes in the detector.


What is it called when an unwanted material that contains radioactive atoms is present on another material?

It is called contamination when an unwanted material containing radioactive atoms is present on another material. Contamination can occur through direct contact, airborne transfer, or ingestion of the radioactive material. It is important to address contamination promptly to minimize exposure and potential health risks.


What happens to radioactive materials if you do not use them?

That depends on the radioactive material. But whether you use it or not, the radioactive material will decay into other elements over the course of time. The time it takes for half of the material to decay into something else is called the "half-life". The more radioactive the substance is, the faster it decays. The half-life of a radioactive element can be measured from fractions of a second to billions of years.


Where is radioactive material?

There is radioactive material in any country that has done nuclear tests. In The United States of America there were many tests. These were mostly in Nevada. If you were to get clearance to go to the test site you would see the craters everywhere.


What does a radioactive hazard placard on a vehicle indicate?

The radioactive placard on a vehicle indicates that the vehicle carries some amount or regulated radioactive material.
