- 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'.
