Biodosimetry
There is a free biological age test at www.growyouthful.com It asks you about 140 questions, and then makes an estimate of your body's real age. This test was the first available on the internet, and in my opinion is still the best available. It also includes a shorter rate-of-aging test, to give you an idea of whether you are aging faster or slower than average
The error is called interpolation error. It occurs when a measurement falls between the smallest markings on a measuring instrument, requiring an estimate to determine the exact value.
common ancestor by comparing the differences in their DNA sequences. By measuring the rate of mutations in DNA sequences over time, researchers can estimate how long ago two organisms diverged from a common ancestor. This provides insights into the evolutionary history and relationships between different species.
Here is a website that purports to calculate a biological age. They don't explain their methodology, but it seems to be calculated as something like: Your current age MINUS your personal life expectancy (estimated from your family history, health behaviors, etc.) PLUS the US life expectancy for a person of your age and sex . It is not clear how good the estimate of your personal life expectancy is, but my biological age is 10 years below my current age, so it must be right, right? http://www.preventdisease.com/healthtools/articles/health_age.html
Biodosimetry
The method used to estimate a radiation dose by measuring the biological response to an observed dose of ionizing radiation is called biodosimetry. This technique analyzes specific biological markers, such as chromosomal aberrations or gene expression levels, to assess the level of exposure to radiation and estimate the resulting dose received by an individual.

Four point assay refers to an estimate of the potency of a drug by measuring the response it produces in a biological it produces i n abiological preparation
The dicentric chromosome assay is a blood test that can accurately estimate radiation dose. This test looks for changes in the structure of specific chromosomes that can occur after exposure to ionizing radiation, and the frequency of these changes can be used to estimate the amount of radiation received.
The size of a radiation field can be approximated by using shielding calculations based on the type of radiation and energy levels present. This involves considering the source strength, material composition, distance from the source, and shielding effectiveness of the surrounding materials. Computer simulations and mathematical models can also be used to estimate the extent of the radiation field without direct measurement.
A complete blood count (CBC) with differential test can provide information on white blood cell counts, which can be used to estimate radiation dose in cases of acute radiation exposure. Specifically, lymphocyte depletion kinetics can be used to estimate radiation dose.

To estimate radiation dose, the dicentric chromosome assay (DCA) is commonly used. This test involves analyzing blood samples for the presence of dicentric chromosomes, which are indicative of exposure to ionizing radiation. The number of dicentric chromosomes can provide an estimate of the radiation dose received by an individual. Other tests, like the gamma-H2AX assay, may also be utilized for similar purposes.
