Ответ:
The answer; They used a stable isotope and tracked it with a Becquerel counter
An example of stable isotopes is 14-C and 2-H. These types of isotopes have an atomic decay that leaves less radioactive material behind, hence safe for laboratory use and used without harming the normal processes of life being investigated. Bq is the unit preferred for this type of radioactivity.
