For the love of all things science
The fundamental building blocks of matter made up of three subatomic particles called photons, neutrons, and electrons is know as.....
An Atom
What is the half life of cobolt 60?
5.3 years.
What is the half life of esium-137?
30.17 years
Amount of time for one half of original radiative material to decay into radiation and daughter isotope. What is this called?
Half-Life
A unit of measurement to the exposure of ionizing radiation, specifically gamma radiation & x-ray named after the German physicist. What is this unit called?
Roentgen.
What do you call one thousandths of a roentgen?
A Milli Roentgen.
AN atom or molecule with a net electric charge due to the loss or gain of one or more electrons. A positive or negative charged atom or molecule. What is this called that is being described in the question?
A Ion.
What do you call an isotope that is always unstable and thus contains high levels of nuclear energy?
What is a radioactive isotope.
What do you call the removal of electrons from a atom. The essential characteristic of high energy radiations when interacted with matter?
Ionization.
A subatomic particle with about the same mass as a proton but without an electric charge. These subatomic particles are present in all atoms except the hydrogen atom. What is this subatomic particle called?
What is a Neutron.
What do you call the material a radioactive substance decays into?
Daughter Isotope.
What do you call a stable subatomic particle with a negative charge?
Electron.
The process by which the nucleus of a stable atom splits upon impact of another particle and splits into 2 smaller parts. The resulting atoms are not the same element as the parent atom and are considered unstable and radioactive. This is the process by which individual isotopes are created. What is this process referred to.
Nuclear Fission
How much smaller are Beta particles then Alpha particles?
~800
What do you call ionizing particulate radiation, which can be deadly if ingested, inhaled? Not as dangerous as gamma or beta particles. They are easily absorbed by cells.
What are Alpha Particles.
