Finding the Half Life From Activity

Click For Summary
SUMMARY

The discussion centers on the calculation of half-life from a given activity table. The user initially calculated a half-life of 2.34 minutes by halving the initial activity of 36506, which was incorrect. The correct half-life, as stated in the textbook, is 1 minute. The confusion arose from misinterpreting the relationship between activity decay and time, leading to an erroneous conclusion regarding the duration of the half-life.

PREREQUISITES
  • Understanding of radioactive decay principles
  • Familiarity with half-life calculations
  • Basic knowledge of activity measurement in nuclear physics
  • Ability to interpret data tables
NEXT STEPS
  • Study the concept of radioactive decay and its mathematical models
  • Learn how to accurately calculate half-life from activity data
  • Explore the relationship between activity and time in decay processes
  • Review examples of half-life calculations in nuclear chemistry
USEFUL FOR

This discussion is beneficial for students in nuclear physics, researchers in radiochemistry, and anyone involved in calculating half-lives in scientific contexts.

I am meant to deduce the half life from this table (as attached.) I was under the impression that the half life would occur when the initial activity was halved but my answer of 2.34 minutes (from halving the initial activity of 36506) is wrong. Instead, the answer the textbook got was 1 minute. What did I do wrong?

Are you sure these things are related? How can the answer be in minutes when the timing was over hours?
 
The answer was one minute and I got an 2.34 hours (my mistake.) I'm not sure what to do now...
 
The answer of one minute does not match with this question.A quick glance at the table shows the answer is over two hours.
