You can't share the radiation through intercourse or any other type of contact. Read on, for more than you ever wanted to know about external beam radiotherapy!
Radiotherapy is a type of high energy beam. It's at a frequency and energy level high enough that you do not perceive of as visible light, though. It has energy level sufficient to alter some chemicals as it passes through them. DNA is one chemical that is sensitive enough to undergo changes when bombarded by an X-ray beam.
Cancer cells that are actively involved in making DNA (that is, the cell is about to divide) are more easily destroyed or irrepairably altered by X-ray radiation. For this reason, multiple X-ray treatments are used to irradiate a former tumor site. The strategy is to kill the portion of cells in reproductive phase, wait till other cells go into reproductive phase and then get them too... and so forth.
Once the energy beam is turned off, it's gone. It's not like a radioactive substance that lingers. Radioactive materials have unstable atomic nuclei that give off radiation and in so doing, they change to a more stable form. A piece of radioactive material can be used to deliver radiation therapy, but that is a completely different method called "Brachytherapy" as opposed to "External Beam Radiotherapy" which includes X-ray therapy. For people who are undergoing brachytherapy, it is a good idea for them to stay to themselves for a period of time, to minimize the dose of radiation given to other people inadvertantly.
Radiation therapy is useful when the tumor type is known to respond well to radiation, and the tumor location is a reasonable target to shoot with the external beam. If the beam would pass through a lot of stuff that would be severely damaged by it's passage, then perhaps external beam radiation isn't a great idea. Also, if a tumor's location is on something that makes for a moving target, then perhaps one day it gets a good dose of radiation, but on another day, the tumor site has moved well out of the bullseye and the beam misses it entirely.
I suspect that your colon cancer is located in the rectum if you are going to undergo radiation treatments. Colon cancer, although radiosenstive, is typically a bad target. The small intestine is in the way for most of the upper portion of the colon. Also, the transverse colon and the sigmoid colon are highly mobile. The only portion of the colon that makes for a decent radiation target is the rectum. The rectum is fixed in place, and there isn't a lot of other intestine surrounding it.
Rectal cancers can be shrunk by preoperative radiation in order to be surgically removable, or the operative site can be radiated after surgery. Either way, chemotherapy is typically used as well. In some cases (anal canal cancer), X-ray therapy and chemotherapy have become primary, and surgery can be avoided completely.
I hope that helps.

Ultrasounds are supposedly threat-free. yet any such number of issues are discovered to be risky a lengthy time period when they have been used less than that assumption. there is not any radiation coming from ultrasound, yet there are different issues to think about, which consists of rigidity to the fetus and some hypothesis over even if the little ones can listen the sound waves (and if it hurts their ears). only because the FDA says some thing is threat-free, would not propose it is. it is a corrupt corporation that OKs loads of medication that finally end up to be risky for anybody, a lot less pregnant females. I have a intense threat being pregnant so i extremely must have some ultrasounds to verify my twins are growing to be as they ought to. My dad has worked with radiation for years, both interior the militia and interior the own sector, and has achieved some artwork with ultrasound besides. He counseled me to easily have ultrasounds that are medically needed, because we do exactly not recognize each and everything about the technologies and we do not recognize each and every attainable effect of having it achieved. So i am going to bypass the three-d/4D souvenir ultrasounds that are so popluar presently. Years down the line, we would locate that they are not as threat-free as we concept. So, i'd be careful. I see various of those that believe that it ought to no longer be risky if medical doctors are prescribing it. Wow, it is quite gullible. i have had medical doctors prescribe meds to me that are generic to be risky, like Advair. medical doctors are taught that some thing is threat-free and believe it until eventually it is shown in the different case. people also say, properly I had ultrasounds and my infant is healthy. That too, is defective common sense. the topics received't take position until eventually later in life, or maybe as those little ones have little ones of their personal. There are some self sufficient thinkers right here, fortuitously, who recognize that only because they're advised some thing is threat-free, would not unavoidably propose it is. medical doctors do not recognize each and everything and what's threat-free quicker or later, in many cases isn't the subsequent.

Nope, sorry doesn't work like that. If you're healed from your surgery (unless you have a frontal colon resection/stoma) have all the sex you want!
