|isotope purity||≥70 atom % 18O|
|Melting point||0 °C (lit.)|
Water-18O has been used:
- in modern medical diagnostic methods-positron emission tomography;
- as an isotope indicator during biomedical research;
- when setting up large-scale environmental studies;
For example, the use of sulfur dioxide labeled with the Oxygen-18 isotope makes it possible to determine the source of acid pollution after moving the cloud for many hundreds of kilometers.
Thus, Oxygen-18 is extremely successfully used to solve extremely relevant programs in the field of healthcare, ecology, and fundamental sciences.
