AI Thread Summary
To determine the specific activity of radionuclides in sediments, one must calculate the activity of the radionuclide and the mass of the sediment. The specific activity is unique to each nuclide and is directly related to its decay constant. Methods for measuring the radionuclide include separating the element from the sediment or using emission spectroscopy to assess its quantity. Accurate measurements are crucial for effective analysis. Understanding these principles is essential for calculating the specific activity and volume fraction of radionuclides like tritium.

what is the formula to determine the specific activity of radionulcide in sediments
 
Engineering news on Phys.org
One has to determine the activity of the radionuclide and the mass of the sediment. The specific activity of a given nuclide is unique and related to the decay constant.

One might attempt to separate the given element from the sediment and measure the mass, or perhaps measure the quantity (or proportion) present by emission spectroscopy.

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...
