Isotopic signatures of materials find increasing use in forensics allowing disguising the origin of otherwise similar materials and tracking the materials to their common source. For example the isotope signatures of C including moisture and nutrient availability. In case of synthetic materials, the signature is influenced by the conditions during the chemical reaction. The isotopic signature profiling is useful in cases where other kinds of profiling, e.g. characterization of impurity, are not optimal.
A study was published demonstrating the possibility of determination of the origin of a common brown PSA packaging tape by using the carbon, oxygen, and hydrogen isotopic signature of the backing polymer, additives, and glue.
Measurement of carbon isotopic ratios can be used for detection of humiliation of honey. Addition of sugars originated from corn or sugar cane (C4 plants) skews the isotopic ratio of sugars present in honey, but does not influence the isotopic ratio of proteins; in an unadulterated honey the carbon isotopic ratios of sugars and proteins should match. As low as 7% level of addition can be detected
Forensics
A recent development in forensic science is the isotopic analysis of hair strands. Hair has a recognizable growth rate of 9-11mm per month or 15cm per year. Hair growth is primarily a function of diet, especially drinking water intake. The stable isotopic ratios of drinking water are a function of location, and the geology that the water percolates through. 87Sr, 88Sr and Oxygen isotope variations are different all over the World. These differences in isotopic ratio are then biologically 'set' in our hair as it grows and it has therefore become possible to identify recent geographic histories by the analysis of hair strands. For example, it could be possible to identify whether a terrorist suspect had recently been to the Middle-East from hair analysis. This hair analysis is a non-invasive method which is becoming very popular in cases that DNA or other traditional means are bringing no answers.
Sourcing archaeological materials
Isotope analysis has been particularly useful in Archaeology as a means of characterization. Characterization of artifacts involves determining the isotopic composition of possible source materials such as metal ore bodies and comparing these data to the isotopic composition of analyzed artifacts. A wide range of archaeological materials such as metals, glass and lead-based pigments have been sourced using isotopic characterization. Particularly in the Bronze Age Mediterranean Lead Isotope Analysis has been a useful tool for determining the sources of metals and an important indicator of trade patterns.
Some imaging uses radioactive isotopes to see various parts of the body.
Radiometric dating is a method that uses the radioactive decay of isotopes in rocks and other objects to determine their age. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample.
There are three stable isotopes of Chromium 52Cr, 53Cr, and 54Cr.
Isotopes of krypton are: Kr-78, Kr-80 to Kr-84, Kr-86. Kr-83 was used in magnetic resonance imaging.
Carbon is the element that has four isotopes: carbon-12, carbon-13, carbon-14, and carbon-15. Each isotope has a different number of neutrons in its nucleus, resulting in variations in atomic mass.

The "ionizing" type of smoke alarms uses Americium.
Radon has four main isotopes: 210Rn, 211Rn, 222Rn, and 224Rn. Radon-222 is the most stable form.
The isotopes are not manufactured for specific uses, they occur in nature naturally.
