Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'облучать' in a general sense (e.g., sunlight). It is specifically 'облучать рентгеновскими лучами'.
  • The 'X' is part of the English term and should not be translated.

Common Mistakes

  • Using 'radiate' instead of 'irradiate' ('The machine radiates the sample' is incorrect for this meaning).
  • Omitting the hyphen (though 'x-irradiate' is standard, 'X-irradiate' is also acceptable).
  • Confusing with 'irradiate' meaning 'to light up' or 'to make cheerful'.
