Isotopic tracers can be used to take the place of an atom that is part of a molecule with known structure. You can then react that molecule with another and test your sample for your isotope. This allows you to determine the reaction mechanism because you know if your specific atom was involved.
Jacob Sacks has written: 'Isotopic tracers in biochemistry and physiology'
In general a tracer is a substance that can be used e.g. to monitor how a process runs or a volume of material is transported in a medium. The tracer is part of the system that is inspected. Anything can be taken as tracer which is suitable to monitor these processes closely and whose specific property (isotopic ratio, concentration, colour etc.) can be measured sufficiently precisely to allow for a sound interpretation of experimental results. Isotopic tracers can for example be used to monitor how groundwater flows in an aquifer, but for the same purpuses one can also use elemental or molecular tracers.

- Radioactive substances are often used as tracers in medical investigations - They can also be used to treat some conditions such as cancer - Medical diagnostic - Isotopic sources of energy - Tracers in hydrology, biology, agriculture, etc. - Minerals dating in geology - Tracers in chemical industry - Tracers to study damage of metals, building materials, etc. - Radiochemical polymerization - Sterilization of foods, medical equipment, wastes - Smoke detectors - Water detectors and many others important applications. But uncontrolled use of radioactivity may be dangerous; internal contamination or external irradiation must be avoided.

Yes, tracers were in use during that time. The first tracers were developed by the British in 1915.
