Neutron Activation Analysis (NAA) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Weight of Particular Element = Atomic Weight of Element/[Avaga-no]*Specific Activity at Time t
W = M/[Avaga-no]*A_t
This formula uses 1 Constants, 3 Variables

Constants Used

[Avaga-no] - Avogadro’s number Value Taken As 6.02214076E+23

Variables Used

Weight of Particular Element - (Measured in Gram) - Weight of Particular Element is the quantity of a said element present in say, x gram of the sample.
Atomic Weight of Element - (Measured in Gram) - Atomic Weight of Element is the total mass or weight of an atom of the element.
Specific Activity at Time t - (Measured in Becquerel per Kilogram) - Specific Activity at Time t is the activity per unit mass of a radionuclide at time t.

STEP 1: Convert Input(s) to Base Unit

Atomic Weight of Element: 74.9216 Atomic Mass Unit --> 1.24410328662268E-22 Gram (Check conversion here)
Specific Activity at Time t: 35000000000 Becquerel per Gram --> 35000000000000 Becquerel per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W = M/[Avaga-no]*A_t --> 1.24410328662268E-22/[Avaga-no]*35000000000000

Evaluating ... ...

W = 7.2305873886272E-33

STEP 3: Convert Result to Output's Unit

7.2305873886272E-36 Kilogram -->7.2305873886272E-33 Gram (Check conversion here)

FINAL ANSWER

7.2305873886272E-33 ≈ 7.2E-33 Gram <-- Weight of Particular Element

What is Neutron Activation Analysis (NAA)?

Neutron activation analysis (NAA) is a nuclear process used for determining the concentrations of elements in many materials. NAA allows discrete sampling of elements as it disregards the chemical form of a sample, and focuses solely on atomic nuclei. The method is based on neutron activation and thus requires a neutron source. The sample is bombarded with neutrons, causing its constituent elements to form radioactive isotopes. The radioactive emissions and radioactive decay paths for each element have long been studied and determined. Using this information, it is possible to study spectra of the emissions of the radioactive sample, and determine the concentrations of the various elements within it.

What are the applications of NAA?

Neutron Activation Analysis has a wide variety of applications including within the fields of archaeology, soil science, geology, forensics, and the semiconductor industry.
Archaeologists use NAA in order to determine the elements that comprise certain artifacts. This technique is used because it is nondestructive and it can relate an artifact to its source by its chemical signature. This method has proven to be very successful at determining trade routes, particularly for obsidian, with the ability of NAA to distinguish between chemical compositions. In agricultural processes, the movement of fertilizers and pesticides is influenced by surface and subsurface movement as it infiltrates the water supplies.
NAA is used in geology to aid in researching the processes that formed the rocks through the analysis of the rare-earth elements and trace elements. It also assists in locating ore deposits and tracking certain elements
