How Far Do Alpha Particles Travel In Air. Alpha particles, because they are highly ionising, are unable to penetrate very far through matter and are brought to rest by a few centimetres of air or less than a tenth of a m. Because the alpha is a large atom (~4 amu), and has a high charge (+2), it is highly ionizing as compared to other forms of radiation.

While alpha particles travel in short, straight lines, beta particles (some 8,000 times lighter) have long, unpredictable,. Can beta particles pass through air? In order to describe principles of detection of alpha radiation, we have to understand the interaction of radiation with matter.each type particle interacts in a different way.

Actually alpha particles travel great in a vacuum. There is a distance where none alpha particles are registered with the detector. They are lighter than alpha particles, and can travel farther in air, up to several yards. Dust size is important in determining potential associated health hazards.
