Quick answer: Who Is Most Sensitive To Radiation?

Are some people more sensitive to radiation?

Some people are more sensitive to harmful effects of radiation than others.

There are a number of factors that influence an individual’s sensitivity to radiation.

These factors include age, gender, other exposures and genetic factors.

Age – In general, exposed children are more at risk than adults..

How does radiation affect a child?

When given equal radiation doses, the risks for children and adolescents are greater than for adults. Children grow quickly, and their cells are more sensitive to radiation. … As adults age, radiation exposure becomes less of a concern. The body tissues of older patients are less sensitive to the effects of radiation.

What does radiation do to kids?

Radiation can damage healthy cells. This damage can cause side effects such as skin problems, tiredness, and anemia. The type of side effects someone might get depends on the dose of radiation, whether it was internal or external, and the area treated. Many patients have no side effects.

Can radiation cause birth defects?

Large radiation doses to the fetus during the more sensitive stages of development (between weeks 2 and 18 of pregnancy) can cause birth defects, especially to the brain. … They also suffered stunted growth (up to 4% shorter than average people) and an increased risk of other birth defects.

What types of cells are most sensitive to radiation damage quizlet?

Cells that divide very rapidly (spermatozoa and lymphocytes) are extremely sensitive to radiation because they are in the metaphase stage of mitosis more often.

Which is a biological effect of low exposure to radiation?

We tend to think of biological effects of radiation in terms of their effect on living cells. For low levels of radiation exposure, the biological effects are so small they may not be detected. The body has repair mechanisms against damage induced by radiation as well as by chemical carcinogens.

Can a baby absorb radiation?

This can occur when the mother’s abdomen is exposed to radiation from outside her body. Also, a pregnant woman who accidentally swallows or breathes in radioactive materials may absorb that substance into her bloodstream. … Unborn babies are less sensitive during some stages of pregnancy than others.

Why are rapidly dividing cells more sensitive to radiation?

Tissues that are made up of rapidly dividing cells are similarly radiation-sensitive. … Cells that are fully oxygenated tend to be more sensitive than those that are less well-oxygenated. The reasons for this will be discussed later in the lecture.

What is a stochastic effect?

Stochastic effects. Effects that occur by chance, generally occurring without a threshold level of dose, whose probability is proportional to the dose and whose severity is independent of the dose. In the context of radiation protection, the main stochastic effects are cancer and genetic effects.

How long does radiation sickness last?

The prognosis for ARS is dependent on the exposure dose, with anything above 8 Gy being almost always lethal even with medical care. Radiation burns from lower-level exposures usually manifest after 2 months, while reactions from the burns occur months to years after radiation treatment.

Which part of the body is most sensitive to radiation?

For example, since the blood forming cells were one of the most sensitive cells due to their rapid regeneration rate, the blood forming organs are one of the most sensitive organs to radiation. Muscle and nerve cells were relatively insensitive to radiation, and therefore, so are the muscles and the brain.

Which organ is least sensitive to radiation?

Amongst the body cells, the most sensitive are spermatogonia and erythroblasts, epidermal stem cells, gastrointestinal stem cells. The least sensitive are nerve cells and muscle fibers.

Can I be around kids after radiation?

Permanent implants remain radioactive after the patient leaves the hospital. Because of this, the patient should not have close or more than 5 minutes of contact with children or pregnant women for 2 months. Similarly, people who have had systemic radiation therapy should use safety precautions.

What can you not do during radiation treatment?

Its best to avoid fried foods as a precaution during your radiation therapy. Spicy Foods – Plenty of us enjoy spicy foods, but the truth is they could wreak havoc on your body if you eat them while undergoing radiation therapy. Radiation typically causes nausea and loose stools or constipation.
