Introduction to How Radiation Works
Say the word "radiation" to three different people, and you’ll probably get three different reactions. Your aunt may tell you how radiation destroyed her cancer. Your neighbor might mention the "duck and cover" procedures of his day. And your comics loving friend will explain how gamma rays turned Bruce Banner into The Hulk. Radiation comes in many forms and is all around us, all

2012 Nike Free Run 2 Blue Orange Mujeres Entrega Rápida also exposed to radiation from our own inventions medical procedures, televisions,
Nike Free Run 3.0 V4 Gris Mujeres Cada Compra Que Realice cell phones and
2012 Nike Free Run 3.0 Luz Gris Verde Naranja Mujeres Venta microwave ovens. Radiation isn’t necessarily always dangerous. It depends on its strength, type and
Nike Free Run Trainer 3.0 Negro Azul Hombres En Venta the length of
2013 Nike Free Run Líneas Azul Hombres Con Descuento Grande exposure.
Most people will tell you Marie Curie
2012 Nike Free Run 2 Gris Azul Rosa Mujeres Venta Auténtico discovered radiation, along with her husband and research partner
2012 Nike Free Run Tr Fit Azul Hombres Amarillo Para Barato Pierre. And that’s right
Nike Free Run 3.0 V4 Naranja Gris Mujeres Envío Rápido sort of. Curie actually discovered the element radium in 1898, an accomplishment that would make her the first female recipient of the Nobel Prize. However, three years
Nike Free Run 2 Negro Azul Mujeres Outlet Worldwide earlier in 1895, a scientist named Wilhelm Rntgen first discovered X rays and
Wmns Nike Free Run 3.0 V5 2014 Verde Mujeres En Venta the phenomenon of radioactivity (a term later coined by Curie, based on the Latin
Nike Free Run 3.0 grises azules claros Mujeres Envío Rápido word for "ray"). Soon after Rntgen’s discovery,
2013 Nike Free Run Powerlines Negro Rojo Hombres llegada Atención Al Cliente Es Nuestra Principal Prioridad a French scientist named Henri Becquerel attempted to figure out
2012 Nike Free Run 2 Gris Rosa Mujeres 70% De Descuento where X rays came from, and in the process found that uranium emitted a powerful "ray." Marie Curie based

Radiation is energy that travels in the form
Nike Free Run 4.0 2012 Azul Verde Mujeres Envío Rápido of waves (electromagnetic radiation) or high speed particles
Nike Free Run 3.0 V2 Gris Negro Mujeres Venta Auténtico (particulate
Nike Free Run 3.0 V4 blancas púrpuras Mujeres 100% Auténticos y Seguros De Pago radiation). Particulate radiation happens when an unstable (or radioactive) atom disintegrates.
2014 Nike Free Run Gimnasio Blanco Rojo Hombres Con Calidad Auténtico Electromagnetic (EM) radiation, on the other hand, has no mass and travels in
Nike Free Run 3.0 V4 Rojo Púrpura Mujeres Para Barato waves. EM radiation can range from very low
Nike Free Run Powerlines Ii Men Negro Verde Venta energy to very high energy, and we call this span the electromagnetic spectrum.

Sadly, the very thing that gave Marie Curie everlasting life in our history books is what ultimately killed her. In the late 1890s, both Marie and her husband Pierre began suffering various ailments. The
Nike Free Run 2 Gris Rosa Mujeres Liquidación Envío Rápido photon is the base particle for all forms
2014 Nike Free Run Gimnasio Blanco Azul Hombres Para Barato of EM radiation. But what’s a photon? It’s a bundle of

Nike Free Run 3.0 V2 Negro Naranja Mujeres En Venta fact,
Nike Free Run 2 Gris Rosa Mujeres Con Calidad Superior the amount of energy a photon carries makes it sometimes behave like a wave and sometimes like a particle. Scientists call this wave particle duality. Low energy
Nike Free Run Trainer 3.0 Negro Hombres Con El Envío Libre photons (such as radio) behave like waves, while high energy photons

EM radiation can travel through empty space. This differentiates it
Nike Free Run 2 Gris Azul Mujeres Entrega Rápida from other types of waves, such as sound, which need a medium to move through. All forms of EM radiation reside on the electromagnetic spectrum, which ranks radiation from lowest energy/longest wavelength to highest energy/shortest wavelength. The higher the energy,
2012 Nike Free Run 3.0 V2 Gris Verde Mujeres Uk Online Salestore the stronger, and therefore more dangerous, the radiation. The only difference between a radio wave and a gamma ray
Nike Free Run 2 Pinke Blanco Mujeres Hasta 52% De Descuento is the energy level of the photons [source: NASA]. Below is the electromagnetic spectrum at
2012 Nike Free Run 3.0 de pieles blancas púrpuras Mujeres Envío Libre y Vuelve Con Devolución De 30 Días a glance.
Radio: Radio waves have the longest wavelength in the electromagnetic spectrum (up to a football field long). They are invisible to our eyes. They bring music to our radios, sound and picture to
Nike Free Run 3.0 V4 Rojo Púrpura Mujeres Venta Auténtico our
Nike Free Run 3.0 V4 Gris Azul Mujeres Para Hombres Baratos televisions, and carry signals to our cell phones. Cell phone waves are shorter than radio waves, but longer than microwaves.
Microwaves: Also invisible, we use microwaves to heat
2012 Nike Free Run 3.0 V2 Blanco Gris Verde Mujeres Atención Al Cliente Es Nuestra Principal Prioridad our food quickly. Telecommunications satellites use microwaves to transmit
Nike Run Balanza gratuito 2014 Mujeres Gris Naranja Venta voice through the phone. Microwave energy can penetrate haze, clouds or smoke, and thus is useful for transmitting information. Some microwaves are
2012 Nike Free Run Tr Fit Naranja Hombres Venta Auténtico used for radar, like the
2012 Nike Free Run 2 Mujeres Gris Rosa Outlet Worldwide Doppler radar your weatherman uses on the news. The entire universe has
2013 Nike Free Run Líneas Azul Hombres Venta Auténtico faint cosmic microwave background radiation something scientists connect to the Big Bang Theory.
Infrared: Infrared lies
2012 Nike Free Run 3.0 V2 Negro Gris Moda En Venta between the visible and invisible portions of the EM spectrum. Your remote control uses infrared light to change the channel. We feel infrared radiation every
2012 Nike Free Run 2.0 Gris Púrpura Mujeres Sale Barato day via the sun’s heat. Infrared photography can detect temperature differences. Snakes can actually detect infrared radiation, which is how they are able to locate warm blooded prey in total darkness.
Visible: This is the
Nike Free Run 3.0 2012 Verde Plata Mujeres Usted Puede Disfrutar Del Precio y Le Consiguen Mejores Artículos De Calidad Aquí only part of the electromagnetic
Nike Free Run 3.0 V4 Gris Azul Mujeres Entrega Rápida spectrum we can see. We see the
2013 Nike Free Run Líneas Azul Gris Hombres Venta Barato different wavelengths
2012 Nike Free Run 2 Azul Negro Mujeres Para Barato in this band
Nike Free Run 2 Gris Azul Mujeres Venta Hombres of the spectrum as the colors of the rainbow. The sun, for example, is
Nike Free Run Powerlines Rainbow Negro Hombres Venta a natural
Nike Free Run 2 azules amarillas Mujeres Outlet En Venta source of
Nike Free Run 2 Orange Yellow Mujeres Entrega Rápida visible waves. When looking at an
Nike Free Run Trainer 3.0 Negro Azul Hombres En Venta object, our eyes see the color
Nike Free Run 2014 Gris Mujeres rojas Venta Barato of light reflected, and all other colors are absorbed.
Ultraviolet: Ultraviolet (UV) rays are what cause us to become sunburned. Humans can’t see UV rays, but some insects
2012 Nike Free Run 3.0 V2 Gris Naranja Mujeres Para Barato can. Our atmosphere’s ozone layer blocks most UV rays. However,
2012 Nike Free Run 3 Gris Verde Mujeres Venta as our ozone layer depletes due to use of chlorofluorocarbons (CFCs), UV
Nike Free Run 3.0 V4 Rojo Púrpura Mujeres Entrega Rápida levels are increasing. This can lead to
Nike Free Run 2 Gris Rosa Mujeres Para Barato health effects like skin cancer [source: EPA].
X rays: X rays are very high energy light waves. We’re most familiar with their use in a doctor’s office, but X rays also naturally occur in space. But don’t worry, X rays can’t penetrate from outer space
2013 Nike Free Run Líneas Azul Hombres Venta Barato to the Earth’s surface. Read

Gamma rays: Gamma rays have the most energy and shortest wavelength of
Nike Free Run 10o Aniversary azul claro púrpura Mujeres Venta Barato the entire spectrum. Nuclear explosions and radioactive atoms generate these rays. Gamma
Nike Free Run Powerlines Ii Green Men Para Auténtico Barato rays can kill living
Nike Free Run 2 Pinke Blanco Mujeres Para Zapatos Baratos cells, and medical professionals
2012 Nike Free Run Tr Fit Azul Blanco Hombres Envío Rápido sometimes use

Read on to find out the difference between non ionizing and ionizing radiation.
We know today that overexposure to X rays is dangerous, and X ray technicians and patients alike must wear protective gear. However, from the 1930s
2013 Nike Free Run L穩neas Azul Hombres Con El Env穩o Libre to 1950s, shoe
Nike Free Run Powerlines Ii Negro Rojo Hombres Venta Barato sales clerks actually used an X ray
Nike Free Run 4.0 Anti-piel Negro Rosa Mujeres En Venta machine for shoe fitting. Although there were no reported overexposure injuries to customers, employees weren’t so lucky. On the electromagnetic (EM) spectrum, this
Nike Free Run 3.0 V5 Ext Bright Pink Mujeres Sale Barato break occurs between infrared and ultraviolet. Drilling down further, ionizing radiation comes in three main
2012 Nike Free Run 3.0 Negro Azul Mujeres Venta Auténtico types: alpha particles, beta particles and gamma
Nike Free Run Powerlines Ii Verde Blanco Hombres Entrega Rápida a Su Puerta rays. We’ll discuss these types of radiation in more detail later in this article.
Non ionizing radiation is relatively low energy radiation that doesn’t have enough energy to ionize atoms or molecules. It’s located at the low end of the electromagnetic spectrum. Non ionizing radiation sources include power lines, microwaves, radio waves, infrared radiation, visible
2013 Nike Free Run Líneas Azul Hombres Venta Auténtico light and lasers. Although considered less dangerous than ionizing
Nike Free Run 3.0 V4 Negro Azul Mujeres Venta Auténtico radiation, overexposure to non ionizing radiation
Nike Free Run 2014 Gris Púrpura Mujeres Venta Auténtico can cause health issues. Let’s take a look at some examples of non ionizing radiation and
Nike Free Run 3.0 2012 Gris Rosa Mujeres Página Oficial Con 100% De Alta Calidad the safety issues surrounding them.
Extremely low frequency (ELF) radiation is the radiation produced by things like power lines
Nike Free Run 2 Negro Azul Mujeres Para Barato Pero El Real or electrical wiring. There are health concerns associated with magnetic field exposures near
Nike Free Run 4.0 2012 Azul Verde Mujeres 70% De Descuento power lines, and this issue is very controversial. Obviously, ELF radiation surrounds us every day, but hazardous exposure depends on the strength of the
Nike Free Run 3 2012 Negro Rosa Mujeres 70% De Descuento ELF at the source, as well as the distance and duration of exposure. Research on ELF radiation focuses on cancer and reproductive issues.
2013 Nike Free Run Líneas Azul Gris Hombres Entrega Rápida There is no definitive link
Nike Free Run 3.0 V5 Ext Bright Pink Mujeres Envío Rápido between ELF radiation and illness, but studies have
Nike Roshe Run 2014 mujeres rojas Ant-piel Envío Rápido shown some preliminary connections [source: WHO].
Radio frequency (RF) and microwave (MV) radiation come most commonly from radios, televisions, microwave ovens and cell phones. Both RF and MV waves can interfere with pacemakers, hearing aids and defibrillators,
Nike Free Run 2 Gris Azul Mujeres Sale Barato and people should take appropriate precautions.
2012 Nike Free Run 2 Mujeres Gris Rosa 70% De Descuento In recent
Nike Free Run 3.0 V2 Negro Naranja Mujeres Venta years, concerns about cell phone radiation have made headlines. Although there is no proven link between cell phone usage
Nike Free Run 2 Gris Azul Mujeres Outlet Tienda Online 2014 and health issues,
Nike Free Run Powerlines Ii Negro Hombres Luna Para Barato the potential is there. Again, it’s
2012 Nike Free Run 2 2.0 Azul Naranja Mujeres Sale Barato all about exposure. Large amounts of RF exposure can heat tissue, which can damage skin or
Nike Free Run Powerlines Ii Negro Oro Hombres En Venta eyes and raise body temperature. Some experts recommend using a headset or hands free device if you use your cell phone
Nike Free Run 3 de plata Mujeres Orange Venta Barato frequently and for long periods [source: FCC]. You can find out more about cell phones and radiation in our article How Cell Phone Radiation Works.
Our skin and eyes absorb infrared radiation (IR) as heat. Overexposure to IR can result in burns and pain. Ultraviolet (UV) radiation overexposure concerns us because
2012 Nike Free Run 2 Negro Blanco Mujeres Venta Barato there
Nike Free Run 4.0 Mujeres Blue Sky Venta Barato are no
Nike Free Run 2 grises verdes Mujeres Venta immediate symptoms. However, effects can develop quickly afterward in the form of a sunburn or worse. Overexposure to UV radiation can lead to skin

Nike Free Run 2 Negro Azul Mujeres Con La Mejor Calidad cataracts and a compromised immune system [source: EPA]. Besides sunlight, UV sources include black lights and welding tools.
Lastly, lasers emit IR, visible and UV
Nike Free Run 3.0 V4 Negro Azul Mujeres Con El Envío Libre radiation. They can
Nike Free Run Powerlines Ii Men Negro Verde Para Barato be quite dangerous to the eyes and skin.
Nike Free Run 2014 Gris Púrpura Mujeres Con El Envío Libre People who work with lasers should wear
Nike Free Run 3.0 V5 Ext Pink mujeres rojas Venta Barato protective gear on the eyes, hands and arms.
