This has happened to me about 4½ years after radiotherapy, although slightly different symptoms. Didn't initially ejaculate blood, but next time I pee'd, there was blood after I finished peeing, and this went on for a couple of days. I think I did ejaculate a little blood next time too.
Urology consultant happened to call up just after peeing blood for the first time, so they had me in to check kidneys and bladder which were both fine. A flexible cystoscopy showed some blood in my prostate, and when I explained that the blood was after peeing urine (which didn't look bloody so blood wasn't present in the bladder or kidneys), they said it's coming from the prostate, and given I've had radiotherapy it's not surprising, and given my PSA is still undetectable and it's not causing excessive blood loss or problems with clots, it doesn't matter.
It happened a couple more times in the months since and I ignored it, but not again recently.
So you do need to get checked if you pass blood, but not unexpected after radiotherapy.
