Quick Answer: Which Part Of The Body Is Most Sensitive To Radiation?

Which is a biological effect of low exposure to radiation?

Low doses may damage or alter a cell’s genetic code, or DNA.

High doses can kill so many cells that tissues and organs are damaged immediately.

This in turn may cause a rapid body response often called Acute Radiation Syndrome..

How does radiation attack the body?

Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to affect the atoms in living cells and thereby damage their genetic material (DNA). Fortunately, the cells in our bodies are extremely efficient at repairing this damage.

Which organ is most radiosensitive?

digestive tractThe digestive tract is among the most radiosensitive organs in the body and its function, which is partly regulated by gastrointestinal (GI) peptides, can be affected by radiation exposure.

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

Terms in this set (94) Which of the following types of blood cells is the most sensitive to radiation? Lymphocytes are white or colorless blood cells derived from lymphatic tissues. Because of their rapid cell division they are more susceptible to the affects of radiation.

Is bone marrow sensitive to radiation?

The cells in your bone marrow are sensitive to radiation therapy. The number of WBCs, RBCs, and platelets in your body may decrease, depending on the part of your body being treated and the dosage of radiation.

Which organ is least sensitive to radiation?

Reproductive and gastrointestinal cells are not regenerating as quickly and are less sensitive. The nerve and muscle cells are the slowest to regenerate and are the least sensitive cells.

What types of cells are most sensitive to radiation damage?

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. Very sensitive cells are also oocytes and lymphocytes, although they are resting cells and do not meet the criteria described above.

In which phase are cells most sensitive to radiation absorption?

Cells in late G2 and mitosis (M-phase) are the most sensitive to radiation, and cells in late synthesis (S-phase) are the most resistant (Fig.

What organs are affected by radiation?

Effects on organs of the body (somatic effects)Skin. Radiation can cause various types of injury to the skin, depending on the dose and conditions of exposure. … Bone marrow. The blood-forming cells of the bone marrow are among the most radiosensitive cells in the body. … Gastrointestinal tract. … Reproductive organs. … Lens of the eye. … Brain and sensory organs.

How will you protect yourself from radiation?

Staying inside will reduce your exposure to radiation.Close windows and doors.Take a shower or wipe exposed parts of your body with a damp cloth.Drink bottled water and eat food in sealed containers.

How cell phone radiation affects the body?

If RF radiation is high enough, it has a ‘thermal’ effect, which means it raises body temperature. There are concerns that the low levels of RF radiation emitted by mobile phones could cause health problems such as headaches or brain tumours.
