High-energy electromagnetic waves (x-rays, gamma rays)
Particles (alpha particles, beta particles, neutrons)
Alpha particles are energetic helium nuclei emitted by some radionuclides with high atomic numbers (eg, plutonium, radium, uranium); they cannot penetrate skin beyond a shallow depth (< 0.1 mm).
Beta particles are high-energy electrons that are emitted from the nuclei of unstable atoms (eg, cesium-137, iodine-131). These particles can penetrate more deeply into skin (1 to 2 cm) and cause both epithelial and subepithelial damage.
Neutrons are electrically neutral particles emitted by a few radionuclides (eg, californium-252) and produced in nuclear fission reactions (eg, in nuclear reactors); their depth of tissue penetration varies from a few millimeters to several tens of centimeters, depending on their energy. They collide with the nuclei of stable atoms, resulting in emission of energetic protons, alpha and beta particles, and gamma radiation.
Gamma radiation and x-rays are electromagnetic radiation (ie, photons) of very short wavelength that can penetrate deeply into tissue (many centimeters). While some photons deposit all their energy in the body, other photons of the same energy may only deposit a fraction of their energy and others may pass completely through the body without interacting.
Because of these characteristics, alpha and beta particles cause the most damage when the radioactive atoms that emit them are within the body (internal contamination) or, in the case of beta-emitters, directly on the body; only tissue in close proximity to the radionuclide is affected. Gamma rays and x-rays can cause damage distant from their source and are typically responsible for acute radiation syndromes (ARS—see Radiation Exposure and Contamination : Acute radiation syndromes (ARS)).
Check out my first "Proton". Hilarious.
See how a Proton Waja driven by one of Japanese drivers from SuperGT.The Porsche Cayman was also there for track testing during the 2007 SuperGT Sepang unofficial ,test day.Drivers testing the newly laid track with their rented cars
note : it was a stock Waja .Unmodified and a rented vehicle.
Part 2 video of our in-car video footage for the 15th July 2007 ;Sunday Track Day in Sepang International Circuit.Two cameras were mounted on a Proton Wira 4G63 turbo.For in-car camera service please contact us.
This is a spoof on how Proton should do their ads. We're helping Proton to save up on advertisement expenditure by NOT paying Godzilla and NOT coming up with nonsensical, retarded commercials. This commercial spoof made by Terato Dot Com shows how Proton cars are viewed by the majority of Malaysians. Thanks to the improved ride and handling by Lotus, this GTi is a gem. Well, almost...

*******www.videokl**** Proton Saga BLM
video pelancaran Proton saga Baru - proton saga BLM
The New Proton Saga BLM launching by Pak Lah
Hot and Sexy Proton saga will be hit market on 18th of jan 2008
and its suitable for any age includes younger sexy teens or as family car.
The funny thing is most of the design is said to be copycat from others established car.
That's normal since big name of car manufacturer also does copy some deisgn from their competitors.

for more hot car video,
