This depends upon the radioactive challenge. Boron has a high neutron capture cross-section, hence the huge quantities of boron used to help sanitize the Chernobyl and Fukishima reactors.
But ordinarily, simple massive materials such as massive concrete or lead are materials of choice.
Possible external irradiation and internal contamination; radium is strongly radioactive ad dangerous.
Patients receiving brachytherapy do become temporarily radioactive
Patients receiving intracavitary radiation do become temporarily radioactive
1. Uranium is a possible polluting agent of the natural environment.2. Uranium is a toxic and a radioactive chemical element.3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated.If working responsibly most of the disadvantages call very limited. And are the major advantages of using uranium especially as nuclear fuel..
Uranium is radioactive, and contamination of water, air or the human system can be fatal or permanently mutate a person or living animal's body, therefore, it is advised not to use uranium and instead use some safer resource.
Thorium can be dangerous, especially when powders are inhaled, because is a radioactive element.
Einsteinium is an artificial element, radioactive and probably toxic; toxicological studies don't exist.
Its Lead. thick lead shields or badges are used to block radiations.
Usually lead is used for shielding, however I believe Boron is used to in a sense "neutralize" radioactive material. I believe this was discussed in possible solutions for Fukashima
Lead is most commonly used for this. An example is the lead jacket the put over you when you get an x-ray at the dentists'.
Zeus protects assemblies of people, councils, and families.
it is just radioactive ok hesh people
the bottom line is that when smoke gets into the detector, it's electrical current is interrupted, causing the alarm to sound (which im guessing you already knew) I'm not totally sure why the radioactive element (americium-241) has to be in there, but what I DO know (contrary to what the previous poster put) is that the alpha rays produced by the radioactive element are NOT strong enough to escape, and therfore pose NO harm whatsoever to people around it.

People in the science olympiad even Crime Busters where you are given a crime and different samples, substences etc... and must solve it using scientific teniques :)
it is like a door it protects things or people inside it is like a door it protects things or people inside it is like a door it protects things or people inside
