Page 2: Mathematical Description of Radioactive Decay
The second page delves into the mathematical aspects of radioactive decay, particularly focusing on the concept of half-life and its practical applications in measuring radioactive decay.
Definition: Half-life t1/2 is the time required for half of the initial number of radioactive nuclei to decay.
Example: After two half-lives, the number of radioactive nuclei becomes No/2², after three half-lives No/2³, and so on, where No is the initial number of nuclei.
Highlight: The decay curve shows an exponential decrease in the number of radioactive nuclei over time, which is characteristic of the loi de décroissance radioactive.
The page includes a graphical representation showing how the number of radioactive nuclei decreases over time, illustrating the exponential nature of radioactive decay.
Vocabulary: Period T - alternative term for half-life, representing the time needed for the radioactive sample to reduce to half its initial amount.
