This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...

It consists of using radiation in its different forms (X-rays, Gamma rays, particles) to harm and destroy tumours, either alone or in combination with surgery or chemotherapy. Radiotherapy is either ...

The thicker the substance, the more the radiation is absorbed. Alpha, beta and gamma radiations penetrate materials in different ways. Alpha radiation is the least penetrating. It can be stopped ...

This is done by choosing isotopes that: Positron emission tomography (PET) scans use a positron emitter ... in the patient’s body and produce gamma rays which can be detected outside the body.
