National Laboratory of Atomic, Molecular and Optical Physics with optical frequency combs they form the Polish Optical Atomic Clock (POZA). The POZA is a state-of-the-art optical atomic clock, collaboratively developed by scientists from the University of Warsaw, Jagiellonian University, and Nicolaus Copernicus University. The optical clocks' experimental group at KL FAMO is conducting research on, i.a., black-body radiation influence on the atomic transitions, shapes of molecules potentials by photoassociation spectroscopy, and on topological defects dark matter The studies of the quantum optics group are focused on experimental verifications of fundamental quantum mechanics predictions. In particular, the Laboratory is especially interested in quantum metrology, quantum information and quantum key
Ionizing radiation cancer, and death. Ionizing radiation is categorized by the nature of the particles or electromagnetic waves that create the ionizing effect. These have different ionization mechanisms, and may be grouped as directly or indirectly ionizing. Any charged massive particle can ionize atoms directly by fundamental interaction through the Coulomb force if it carries sufficient kinetic energy. This includes atomic nuclei, electrons, muons, charged pions, protons, and energetic charged nuclei stripped of their electrons. When moving at relativistic speeds these particles have enough kinetic energy to be ionizing, but relativistic speeds are not required. For example, a typical alpha particle is
