Why the radioactive material must be placed in a box of lead?
Radioactive materials emit dangerous radiation; most of this will be blocked by a box of lead.
Which equation correctly represents the alpha decay of polonium 214?
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
When bismuth 214 emits a positron the remaining daughter nucleus is what?
lead
Where do radioactive atoms start on the periodic table?
After lead, all elements on the periodic table have only radioactive isotopes.
Radium is stored in lead containers because?
Radium is radioactive and lead is a good radiation shield.
Is any isotope of lead is radioactive?
many. one example is lead-214 with a halflife of 26.8 minutes.
What particle is emitted when lead-214 21482Pb undergoes natural radioactive decay to bismuth-214 21483Bi?
An alpha particle, 42He
Why lead is not a radioactive element?
Some isotopes of lead are radioactive: 200, 201, 202, 203, 205, 209. 210, 211, 212, 213, 214, etc. But these do not occur at detectable levels in natural lead.
Does uranium decay to lead in one step?
No, it's a long chain. The decay sequence is: Uranium-238 to thorium-234 to protactinium-234 to Uranium-234 to thorium-230 to radium-226 to radon-222 to polonium-218 to lead-214 to bismuth-214 to polonium-214 to lead-210 to bismuth-210 to polonium-210 to lead-206 which is its final stable form. Radioactive decay occurs when an unstable (radioactive) isotope transforms to a more stable isotope, generally by emitting a subatomic particle such as an alpha or beta particle (helium nucleus or electron). The half-life of one of the elements above can be shorter than a millisecond (Po-214) or as long as 4.5 billion years (U-238).
Is lead a radioactive element?
No.
What is the radioactivity for lead?
The main lead isotopes 206Pb, 207Pb and 208Pb, are not radioactive. It does have traces of radioactive isotopes, but the quantity is so small that lead's radioactivity can be considered zero. It is however toxic if ingested.
Which path would decay polonium 218 to bismuth 214?
Polonium-218 decay to lead-214.
What are the release dates for Lonelygirl15 - 2006 A New Lead 1-214?
Lonelygirl15 - 2006 A New Lead 1-214 was released on: USA: 18 June 2007
Why the radioactive material must be placed in a box of lead?
Radioactive materials emit dangerous radiation; most of this will be blocked by a box of lead.
Why do we put in lead chamber for radioactive element?
Radioactive elements always emit hazardous radiations.Lead metal absorbs these radiations .Hence we put any radioactive element in a lead chamber.
What radioactive element turns to lead when it has lost lots of energy?
It is uranium that is changed into lead during radioactive decay. Note that there are a number of intermediate steps in the conversion of uranium into stable lead. The uranium does not change directly into lead. The uranium atom undergoes decay, and a radioactive daughter product appears. This continues with radioactive daughters appearing at the end of every step - until lead appears.
Lead is considered as which pollutant?
Radioactive pollutants
