What tissues are more sensitive to radiation?
As a result of these epidemiological studies, it was found that the mammary gland, skin, and colon, etc.
are tissues and organs that are easily affected by radiation and develop cancer..
Which phase of cell cycle is most sensitive to radiation?
The cell cycle phase also determines a cell’s relative radiosensitivity, with cells being most radiosensitive in the G 2-M phase, less sensitive in the G 1 phase, and least sensitive during the latter part of the S phase.
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 type of radiation can fully penetrate the human body?
Gamma raysGamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA.
What are the symptoms of radiation sickness?
Initial signs and symptomsNausea and vomiting.Diarrhea.Headache.Fever.Dizziness and disorientation.Weakness and fatigue.Hair loss.Bloody vomit and stools from internal bleeding.More items…•
What is the main source of natural background radiation?
Natural sources of background radiation include: cosmic rays – radiation that reaches the Earth from space. rocks and soil – some rocks are radioactive and give off radioactive radon gas. living things – plants absorb radioactive materials from the soil and these pass up the food chain.
What is the most radiosensitive tissue?
Actively dividing cells that are less differentiated tend to show higher radiosensitivity. On the other hand, nerve tissues and muscle tissues, which no longer undergo cell division at the adult stage, are known to be resistant to radiation. …
How do you detox from radiation?
Decontamination involves removing external radioactive particles. Removing clothing and shoes eliminates about 90 percent of external contamination. Gently washing with water and soap removes additional radiation particles from the skin.
How can I protect my body 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.
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 tissues are most affected by ionizing radiation?
The tissues most affected by radiation are those that undergo rapid replacement, such as bone marrow, the lining of the gastrointestinal tract, and skin. Slower-growing tissues, such as those of the brain and liver, require either high doses of radiation or prolonged exposure before they show symptoms of degeneration.
What are stochastic effects of radiation?
Effects that occur by chance and which may occur 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 effect is cancer.
Is radiation good or bad?
Although it can be destructive, radioactivity can also be beneficial, especially when it comes to medical tests and certain medical treatments. Not only can radiation find tumors within the body, it can also destroy them or slow their growth.
What is the law of Bergonie and Tribondeau?
law of Bergonié and Tribondeau A fundamental law of radiation biology that states that the radiosensitivity of a tissue is increased the greater the number of undifferentiated cells in the tissue, the greater the mitotic activity, and the greater the length of time that they are actively proliferating.
