Bone and metal absorb much more X-radiation and are radiopaque, so their images are white. Most soft tissues in the body are composed mainly of water and appear as shades of grey.
Likewise, which type of cells or tissue is the most sensitive to radiation 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.
Also, which organ is most radiosensitive? The 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. However, very little is known about the effect of whole-body radiation on blood GI peptides.
Beside this, which of the following is the most common result of cell irradiation?
B. Sterilization: The most common result of cell irradiation would be complete recovery.
What is the most common type of damage done to cells by radiation?
Deletion of DNA segments is the predominant form of radiation damage in cells that survive irradiation.

Which tissues are the most sensitive to radiation?
Lymphocytes (white blood cells) and cells which produce blood are constantly regenerating, and are, therefore, the most sensitive. 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.Which of the following types of radiation is classified as electromagnetic?

Which of the following radiation monitoring devices is considered to be the most accurate?
Which of the following radiation monitoring devices is considered to be the most accurate? Optically stimulated luminescence dosimeter (OSL); OSL dosimeters are accurate to 1 mrem. Thermoluminescent dosimeters are accurate to 5 mrem and a film badge is only accurate to 10 mrem.Which stage of cell division is most radiosensitive?
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 type of PID would be most effective in reducing patient exposure?
The long (12 to 16 inch) PID is more effective in reducing exposure to the patient than a short (8 inch) PID because there is less divergence (separation) of the beam.Which type of radiation has a negligible mass and a charge of +1?
D) one proton. Which type of radiation has a negligible mass and a charge of +1? Phosphorous-32 is used for organ imaging.What form of ionizing radiation can penetrate deeply into body tissue?
gamma raysAWhat is the most radiosensitive area of the eye?
lensWhat is a stochastic effect?
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.What is the process of cell division of somatic cells called?
Mitosis is how somatic—or non-reproductive cells—divide. In mitosis, the important thing to remember is that the daughter cells each have the same chromosomes and DNA as the parent cell. The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes.What is the process of cell division of the reproductive genetic cells called?
In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).How many REM is 1000 mrem?

How does oxygen retention affect radiosensitivity?
Nearly all the biological materials studied have shown that, as oxygen concentration is increased from anoxia to that of air, there is a sharp, approximately threefold, increase in radiosensitivity; but sensitivity is little enhanced, if at all, with higher concentrations.Which time frame is the most critical for limiting radiation exposure to an unborn fetus of an employee?
Radiation risks are most significant during organogenesis and the early fetal period, somewhat less in the second trimester, and least in the third trimester. CNS sensitivity is highest about the eighth week postconception; fetal doses in the range of 1,000 mGy result in a high probability of severe mental retardation.What is the unit for radiation exposure in air?
Exposure describes the amount of radiation traveling through the air. Many types of radiation monitors measure exposure. The units for exposure are the coulomb/kilogram (C/kg, international unit) and the roentgen (R, U.S. unit).What is the unit for Air Kerma?
jouleWhat does LD 50 30 and SED 50 refer to?
The dose of radiation expected to cause death to 50 percent of an exposed population within 30 days (LD 50/30). Typically, the LD 50/30 is in the range from 400 to 450 rem (4 to 5 sieverts) received over a very short period.What organs are affected by 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.What is the most radioresistant tissue?
The differentiated fixed postmitotic cells are the most radioresistant. This class includes the long-lived neurons, skeletal muscle cells and erythrocytes. Carcinogenesis is the most important late effect of ionizing 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 is the most sensitive organ in our body?
Human skinWhich 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 tissue is the most sensitive to radiation therapy VTNE?
Bone marrowWhich of the following humans is most radiosensitive?

Radiosensitive tumours are tumours which respond well to radiotherapy. Radiotherapy may be effective alone, or may require the addition of cytotoxic chemotherapy as in the more advanced stages of a Wilm's tumour and Hodgkin's disease. This group includes: malignant lymphomas.What is the law of Bergonie and Tribondeau?
The law of Bergonie and Tribondeau is that the radiosensitivity of a biological tissue is directly proportional to the mitotic activity and inversely proportional to the degree of differentiation of its cells. The more it differs from healthy tissue, the greater its radiosensitivity will be.What is the first sign of too much radiation?

How can you reduce cell phone radiation?
Steps to Reduce Radio Frequency (RF) Exposure- Reduce the amount of time spent using your cell phone.
- Use speaker mode, head phones, or ear buds to place more distance between your head and the cell phone.
- Avoid making calls when the signal is weak as this causes cell phones to boost RF transmission power.
What is a dangerous level of radiation?
To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite risk of cancer and other diseases.Which type of radiation is the smallest in size?
gamma radiationHow can 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 do you rid your body of radiation?
Potassium iodide (ThyroShield, Iosat).Iodine is essential for proper thyroid function. If you're exposed to significant radiation, your thyroid will absorb radioactive iodine (radioiodine) just as it would other forms of iodine. The radioiodine is eventually cleared from the body in urine.
