Tau leptons have a lifetime of {{val|2.9|e=-13|u=s}} and a [[mass]] of {{val|1776.82|u=MeV/c2}} (compared to {{val|105.7|u=MeV/c2}} for muons and {{val|0.511|u=MeV/c2}} for electrons). Since their interactions are very similar to those of the electron, a tau can be thought of as a much heavier version of the electron. Because of their greater mass, tau particles do not emit as much [[bremsstrahlung|bremsstrahlung radiation]] as electrons; consequently they are potentially highly penetrating, much more so than electrons. However, because of their short lifetime, the range of the tau is mainly set by their decay length, which is too small for bremsstrahlung to be noticeable: their penetrating power appears only at ultra high energy (above [[PeV]] energies).<ref>
