One of the hazards of nuclear explosion is the generation of sr and its subsequent incorporation in place of calcium in bones.
this nuclide emits î² rays of energy 0.55 mev, and has a half life of 28.1 y.
suppose 1.00 î¼g was absorbed by a newly born child.

how much will remain after (a) 18 y (b) 70y if none is lost metabolically?

h let me think

answer; i believe the correct answer is (solid gold);

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

you need to have a picture of the atom that way we can answer it
