Another way to look at this is that if the radiation intensity is cut in half; the source will have only half as many curies as it originally had. They allow us to determine the ages of very old artifacts. After another 86 minutes, half of the 5 grams of barium-139 would decay into lanthanum-139; you would now have 2.

Zz٧zym=e{]m ,how does the half-life affect an isotope. A radiographer who works with radioisotopes needs to know the specific half-life to properly determine how much radiation the source in the camera is producing so that the film can be exposed properly. It is important to recognize that the intensity or amount of radiation is decreasing due to age but not the penetrating energy of the radiation. ìûîx:mo‡ãyóôe÷ý ”Úõýµ{ò´;ô©´ýyò²ûèɓ¾ë» Ÿwÿ»{ôãÏw‡îÑËÇ݇c÷èÙãîØ=úÞãîÜ=êo. Let s look closely at how the half-life affects an isotope. You will learn more about carbon dating in the next sub-unit radioactive isotopes in dating.

By determining how much of the carbon-14 has transmutated, scientist can calculate and estimate the age of a substance. [[6f$wy[sfo$@h_Á|f1qe_;:x6nw&9b#Ёp`#ӧolz.
