cricket20 [7]

Answer:

The three types of nuclear radiation in increasing order of penetrating power are ____.

alpha, beta, gamma

Explanation:

Alpha Ray: This has the least penetrating power because the particles produced during decay are large in  quantity but they have a very low energy which dosent alow them to move far through space because the are ususally blocked.

Beta ray : they have more penetrating power than alpha rays because they a bit higher in energy and quantity {size}

Gamma Ray;  this has the most penetrating power. they are highly powerful  waves but do little at ionization of other atoms or molecules.  it penetrates through molecules very easily due to its size and energy.
