Brief Answer:
3-4 days

Detailed Answer:
Hello,

sexual intercourse should be safe 3-4 days after exposure. The radiation specialist may measure your radiation levels after a couple of days after treatment. Please note that sleeping with anybody for the whole night should be delayed until at least one week has passed.
