Alpha - a helium nucleolus, energetic but easily stopped.
Beta - an electron, any metal foil will stop
Gamma - hard radiation (photons), hard to shield from.
These were just the first 3 known;
now have neutrinos, neutrons, "name a particle"
Relative means that it is compared to something. For example, the relative charge of a proton is +1 and it is relative to that proton. The relative charge of an electron is -1 relative to protons. That means it is exactly the same, but opposite. The relative charge of an up quark is +2/3, and that means that the charge of that quark is 2/3 of the charge of the proton. It depends what it is compared to.
3 H2O2 means that the solution contains 3 hydrogen peroxide by volume. This indicates the concentration or strength of the hydrogen peroxide in the solution.
The three methods of heat transfer are: (1) Conduction - particles bump into other particles, transferring energy. (2) Convection - moving masses carry heat with them. Especially, hot air (for example) tends to rise up, because of its lower density - the heat difference itself causes the currents. (3) Radiation. Objects radiate electromagnetic radiation, depending on their temperature. (The amount of energy radiated increases quickly at higher temperatures.)
Ionizing radiation causes some of the atoms it strikes to be ionized. There are several different types: alpha particles, beta particles, neutrons, gamma rays, x-rays, and ultraviolet light. Non-ionizing radiation, which does not ionize atoms, includes visible light, infrared light, radio waves, and so on.To understand the biological effects of radiation we must first understand the difference between ionizing radiation and non-ionizing radiation. In general, two things can happen when radiation is absorbed by matter: excitation or ionization.Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.Because living tissue is 70-90% water by weight, the dividing line between radiation that excites electrons and radiation that forms ions is often assumed to be equal to the ionization of water: 1216 kJ/mol. Radiation that carries less energy can only excite the water molecule. It is therefore called non-ionizing radiation. Radiation that carries more energy than 1216 kJ/mol can remove an electron from a water molecule, and is therefore called ionizing radiation.Related links are provided below.
Hydrogen-3, also known as tritium, is a rare isotope of hydrogen that is primarily produced by the interaction of cosmic rays with atmospheric gases. It can also be produced artificially in nuclear reactors or particle accelerators by bombarding lithium with neutrons. Tritium is used in various applications, such as in nuclear weapons, research, and as a radiation source in certain types of lighting.

3 distinct types of muscle strength; endurance, explosiveness, and max strength,
The three types of radiation that are typically blocked from reaching Earth's surface are gamma rays, X-rays, and most of the ultraviolet radiation from the sun. Earth's atmosphere absorbs and scatters these types of radiation, protecting living organisms from their harmful effects.
There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
The three types of radiation with short wavelength and high frequency are X-rays, gamma rays, and ultraviolet (UV) radiation. These forms of radiation have energetic photons and can have harmful effects on living organisms if exposure is not controlled.
A relative cell reference is one that changes when a formula is copied. It has no dollar symbols in it. There are 3 types of cell reference: Relative, Mixed and Absolute.B3 is a relative reference. $B3 or B$3 are mixed references. $B$3 is an absolute reference.Relative cell references change, but the cell itself does not change.Relative
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through a material, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.
I hope there are only two types. The Absolute and Relative poverty.
The three main types of nuclear radiation are alpha particles, beta particles, and gamma rays. Alpha particles are helium nuclei consisting of two protons and two neutrons, beta particles are high-energy electrons or positrons, and gamma rays are high-energy electromagnetic waves.
There are generally considered to be three main types of strengths: physical strength, mental strength, and emotional strength. Each type plays a role in helping individuals navigate challenges and achieve their goals in different areas of life.
I find this video helpful: http://www.youtube.com/user/JacobWolfarth --- There are 4 things you can work on: 1. Your weight/body composition 2. Your relative strength 3. Your rate of force development (or explosive strength) 4. Reactive/Plyometric strength.
