同位体研究所 List of Products and Services

Stable isotopes have been used in ecosystem research, earth sciences, and resource exploration. There are over 100 types of elements on Earth. While the "protons" that determine the properties of elements are the same, the number of "neutrons" differs, resulting in atoms that have the same properties but different weights (masses). This is called "isotopes." For example, in the case of hydrogen, there is hydrogen with one proton, deuterium with one proton and one neutron, and tritium with one proton and two neutrons. Among these isotopes, there are two types: radioactive isotopes, which are unstable and emit radiation over time, releasing neutrons and changing their atomic number, and stable isotopes, which exist stably. For instance, in atmospheric nitrogen, ¹⁴N accounts for 99.635%, while ¹⁵N, which has one more neutron and is heavier than ¹⁴N, exists at 0.365%.
