Terabecquerel

Terabecquerel (TBq) is a unit of radioactivity in the International System of Units (SI). It is equivalent to 10^12 becquerels (Bq). The becquerel is defined as one decay per second. Therefore, one terabecquerel represents one trillion decays per second.

The terabecquerel is a large unit and is typically used to measure the activity of significant quantities of radioactive material, such as in nuclear power plants, research reactors, or in the production of radioisotopes for medical or industrial applications. For instance, spent nuclear fuel or large quantities of radioactive waste might be measured in terabecquerels.

The unit was named in honor of Henri Becquerel, a French physicist who discovered radioactivity. While the becquerel is the SI unit for radioactivity, older units such as the curie (Ci) were also historically used. One terabecquerel is approximately equal to 27.03 curies. The use of terabecquerels is common in scientific literature and regulatory contexts when dealing with high levels of radioactivity.
