Basic type of radiation that has * Charged subatomic particles (alpha and beta radiation). * Subatomic particles carry energy and have mass.

Groups exposed to radiation that are * Individuals working directly with radiation (Rad Techs, Flight Attendants, Nuclear Reactor Workers). * Exposed to working environment such as in radiology and are monitored for radiation exposure with dosimeters.

source of ionizing radiation that * Results from deposits of Uranium, Thorium, and other radionuclides in the Earth. * Can be found all throughout nature such as in the soil, water, and vegetation.

2 Groups exposed to man-made radiation

* Its properties include: Frequency, Wavelength, Velocity, and Amplitude. * Travel at the SPEED OF LIGHT * 3 x 10^8 m/s or 300,000 km/s or……..186,000 miles/s

* Originates in outer space through heavenly bodies such as the sun and stars. * Source of natural background radiation. * Composed of particulate and electromagnetic radiations.

a type of radiation that does not remove electron from atoms

source of ionizing radiation that is * Found inside the human body through the water we drink or the food we eat * Have always been with us and contribute an equal dose to humans

Type of ionizing radiation that * Includes uncharged particles such as photons or neutrons. * Occurs from an ionization that sets free a single electron with insufficient energy to produce multiple ionization events.

Natural Environment Radiation composes of what fours?

a type of radiation that removes electrons from atoms and molecules

the radioactive gas produced by uranium

2 Basic Types of Radiation

Type of Particulate Radiation that is * Equivalent to a Helium nucleus (Consists of 2 protons and 2 neutrons). * Atomic mass is approximately 4 amu. * Large and exerts great electrostatic force. * Emitted only from heavy elements

* Primarily produced during radioactivity of an unstable atom. * Must be in motion and possess sufficient kinetic energy to cause ionization.

* The largest source of natural environmental radiation. * Alpha emitter. * Contributes to radiation dose only to the lungs. * Can be found in all Earth-based material such as concrete, bricks, and gypsum wallboards.

The intensity of terrestrial radiation is highly dependent on the what of the area

largest man-made source of ionizing radiation (3.2 mSv/vr).

sources of ionizing radiation that * Results in an annual dose of 3.2 millisiverts. * Artificial. * Used in many ways such as medical procedures, consumer items, and nuclear energy.

sources of ionizing radiation that are this * Nuclear Power Plants * Bataan Nuclear Power Plant * Chernobyl * Fukushima * Three Mile Island

type of ionizing radiation that * Includes charged particles that have enough energy to remove electrons or ionize molecules. * Can cause multiple ionization events.

Alpha Radiation, Beta Radiation, X-rays, Gamma rays are types of what radiation?

The intensity of cosmic radiation on Earth increases with what?

* Results in an annual radiation dose of approximately 3 millisieverts. * Human evolution has been influenced by this

source of ionizing radiation that is the following: * Diagnostic X-rays - largest man-made source of ionizing radiation (3.2 mSv/vr). * Computed Tomography * Fluoroscopy * PET Imaging (Fluorine-18) * Nuclear Medicine Imaging (lodine-131, Tc 99m, Co-60, etc.)

Type of Particulate Radiation that is * Safe if intercepted outside of the body (intercepted by layers of the skin); Intense when intercepted inside the body (Inhaled Radon gas irradiate the lungs).

type of group exposed to radiation * Any individual not working directly with radiation (civilians). * Exposed to consumer products, radiation from nuclear fuel cycle, residual fallout from nuclear weapons and accidents.

emission of energy through space. - Can move as electromagnetic waves or subatomic particles (Wave-Particle Duality).

Type of Particulate radiation that * Differ in terms of mass and charge. * Carry a negative charge but differ from electrons by its origin (nucleus). * Range is longer; 10-100 cm in air and 1-2 cm in soft tissue.

Type of Particulate Radiation that has an * Average kinetic energy = 4-7 MeV * ionizes approximately 40,000 atoms for every centimeter of travel through the air * Energy is lost quickly because of the amount of ionization. * Travels 5 cm in air; 100 um in soft tissue.
