26. your mother will soon undergo some medical testing that will require her to swallow a radioactive

isotope as a tracer. she is nervous about having a radioactive substance in her body even though the

radiologist told her not to worry, as the isotope has a half-life of only 7 minutes. explain to her what

a half-life is, and the significance of the half-life being 7 minutes.

Most radioactive materials decay and they mostly have a decay rate. The time it takes for half of a radioactive material to decay is called half life.

The 7 minute significance of half-life simply points to the total time it takes after which half of the radioactive material would have completely decayed,

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
