Tetrads come and go, according to NASA lunar eclipse expert Fred Espenak. Some centuries have several, and the 21st century will have eight. However, there were none between 1600 and 1900.

The radioactive part of the radiopharmaceutical that emits radiation, known as gamma rays (similar to x-rays), is then detected using a special camera called a gamma camera. This type of camera allows the nuclear medicine physician to see what is happening inside your body. During this imaging procedure, the patient is asked to lie down on a bed and then the gamma camera is placed a few inches over the patientâs body. Pictures are taken over the next few minutes.
