Reference: Isotope Half-Life Chart

Isotope | Product| 50 percent Life

Carbon-14| Nitrogen-14| 5730 years

Potassium -- 40| Argon - 40| 1, 280 million years

Rubidium - 87| Strontium -8 7| 48, 800 million years

Thorium - 232 | Lead – 208| 16, 010 , 000, 000 years

Uranium - 235| Lead - 297| 704 million years

Uranium - 238| Lead - 206| 4, 470 million years

Activity 1 – Adjusted

Place important computer data from Activity 1 in the appropriate boxes below. Estimate the age of the calibration requirements using the following information.

* Small percentage of test remaining sama dengan remaining ppm of sample/initial ppm of sample 2. Age of sample = half-life value of isotope Back button number of half-lives elapsed

Tuned Standard| First ppm| Leftover ppm| Associated with Standard| LowCarbon-14| 12000| 5998| 5730

HighUranium-235| 600000| 151000| 11460

1 . Clarify if the tool appears to be calibrated based on the data you acquired for the reduced Calibration Standard. The scintillation instrument will appear to be calibrated because the test was in low standard.

2 . Explain in case the instrument is apparently calibrated based upon the data you obtained to get the High Calibration Standard.

3. Explain which would be the greatest isotope from your Isotope Half-Life Chart to measure a 3 billion year old example of beauty. Rubidium isotope would be the ideal isotope to work with for that way of measuring because it contains the most years that would be required to measure that span. Despite the help of this kind of isotope the task would be rather difficult to make exact.

Activity two

Place your computer data from Activity 1 in the appropriate packing containers below. Determine the age of the calibration...
