do anyone explain me pl. i would like to know the uncertainty error in measuring the specific activity of the primordial radionuclides
hariprasath said:further on as Th-232 has to be estimated from the soil/sediments. as it is not a gamma ray emitter, the daughter product of Tl-208
hariprasath said:do we need to multiply the amounts by 3. or the counts directly gives the acitivity of the Th-232.
hariprasath said:whether poissons's distribution give the exact value of the errors associated at same instant of time.
Uncertainty error refers to the potential variation or inaccuracy in a measurement or calculation. It is important in scientific calculations because it allows us to understand the limitations of our data and results, and helps us make informed decisions about the reliability of our findings.
Uncertainty error is a measure of the potential variation or inaccuracy in a measurement or calculation, while random error refers to the unpredictable and random fluctuations in a measurement or experiment. Uncertainty error accounts for all possible sources of error, including random error, and is a more comprehensive measure of uncertainty.
Sources of uncertainty error can include instrument limitations, human error, and natural variation in the data. These sources can impact the calculation by introducing potential inaccuracies or variations, which can affect the overall result and its reliability.
The most common method for calculating uncertainty error is through propagation of errors, which involves identifying the sources of error and calculating their individual contributions to the overall uncertainty. This is done by using mathematical formulas and applying them to the data to determine the range of potential values.
To minimize uncertainty error, it is important to identify and control all possible sources of error. This can be achieved by using precise and accurate instruments, following standardized procedures, and repeating measurements multiple times to reduce random error. It is also important to properly document all sources of error and their potential impact on the calculation.
