Textbook Problem

Data from the appendices and the periodic table may be needed for these problems.

44. An old camp?re is uncovered during an archaeological dig. Its charcoal is found to contain less than 1/1000 the normal amount of 14C. Estimate the minimum age at the charcoal, noting that 210 = 1024.

To determine

Minimum age of the charcoal

Explanation

Given:

  t1/2 of 14C= 5730 YearsN/N0= e -λt N = amount of radioactive material at initial stageN0=amount of radioactive material after time tλ = 0.693/t1/2=0.693/5730 Years

Formula used:

  N/N0= e -λt N = amount of radioactive material at initial stageN0=amount of radioactive material after time tλ = 0.693/t1/2=0
