Esto aparece en un texto relativo al átomo que dice: "it requires 900,000 electron-volt protons to penetrate the protective shield in order to smash the nucleus and to release its contents". No sé si sería correcto traducirlo como "protones con una energía de 900.000 electronvoltios". Muchas gracias.

The minimum energy which must be supplied to extract an electron from a solid; symbol , units J(joule), or more often eV (elecronvolt). It is a measure of how tightly electrons are bound to a material.
http://invsee.asu.edu/nmodules/engmod/propwf.html
Protons are observed to be stable and their theoretical minimum half-life is 1×1036 years. Grand unified theories generally predict that proton decay should take place, although experiments so far have only resulted in a lower limit of 1035 years for the proton's lifetime. In other words, proton decay has never been witnessed and the experimental lower bound on the mean proton lifetime (2.1×1029 years) is put by the Sudbury Neutrino Observatory[3].
However, protons are known to transform into neutrons through the process of electron capture. This process does not occur spontaneously but only when energy is supplied. The equation is:
P+ + e- n + νe
where
p is a proton,
e is an electron,
n is a neutron, and
νe is an electron neutrino
The process is reversible: neutrons can convert back to protons through beta decay, a common form of radioactive decay. In fact, a free neutron decays this way with a mean lifetime of about 15 minutes.

Comment: "De lo que menos segura estaba era de si "electronvoltios" era correcto. Muchas gracias a todos."

: Esta unidad de energía se denomina en castellano "electronvoltio" (símbolo: eV).

... protones con energía superior a 0,9 MeV ...
Yo añadiría la palabra 'superior' ya que no se trata de un valor exacto sino de un contenido mínimo de energía a partir del cual tuviera lugar ese fenómeno.
