What medical condition is caused by high radiation exposure?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.
What are three symptoms of high radiation exposure?
Symptoms are anorexia, severe nausea, vomiting, cramps, and diarrhea. Onset occurs within a few hours after exposure.
What are the symptoms of ARS?
Symptoms of ARS
- These symptoms include loss of appetite, fatigue, fever, nausea, vomiting, diarrhea, and possibly even seizures and coma.
- This seriously ill stage may last from a few hours up to several months.
- People who receive a high radiation dose also can have skin damage.
Which of the following is a result of high exposure of radiation Mcq?
Which one of the following is a result of high exposure of radiation? Loss of white blood cells happens due to more exposure to radiation.
What are the three acute radiation syndrome?
It is generally divided into three types: bone marrow, gastrointestinal, and neurovascular syndrome, with bone marrow syndrome occurring at 0.7 to 10 Gy, and neurovascular syndrome occurring at doses that exceed 50 Gy. The cells that are most affected are generally those that are rapidly dividing.
What does ARS do to the body?
The symptoms of ARS can start within the hour of exposure, and can last for several months. Within the first few days the symptoms are usually nausea, vomiting and a loss of appetite….

|---|---|
| Treatment | Supportive care (blood transfusions, antibiotics, colony stimulating factors, stem cell transplant) |
How is ionizing radiation measured?
The energy of ionizing radiation is measured in electronvolts (eV). One electronvolt is an extremely small amount of energy. Commonly used multiple units are kiloelectron (keV) and megaelectronvolt (MeV).
Which of the following is most susceptible to radiation damage?
A fetus is most vulnerable to the effects of radiation. Infants, children, older adults, pregnant women, and people with compromised immune systems are more vulnerable to health effects than healthy adults.
Which one of the following is a result of overpopulation?
3. Which one of the following is a result of overpopulation? Explanation: Due to rapid population growth, there is a pressure on land and other renewable natural resources. Due to over exploitation of forest and water it results in desertification with permanent damage to renewable resources.
What do you need to know about acute radiation syndrome?
CDC Radiation Emergencies | Acute Radiation Syndrome Acute Radiation Syndrome (ARS): A Fact Sheet for the Public Acute Radiation Syndrome (ARS), or radiation sickness, is a serious illness that can happen when a person is exposed to very high levels of radiation, usually over a short period of time.
What happens to the body when exposed to radiation?
A very high level of radiation exposure delivered over a short period of time can cause symptoms such as nausea and vomiting within hours and can sometimes result in death over the following days or weeks. This is known as acute radiation syndrome, commonly known as “radiation sickness.”.
Who is most sensitive to the effects of radiation?
Children and fetuses are especially sensitive to radiation exposure. The cells in children and fetuses divide rapidly, providing more opportunity for radiation to disrupt the process and cause cell damage. EPA considers differences in sensitivity due to age and sex when revising radiation protection standards.
How much radiation is needed to cause neurovascular syndrome?
The neurovascular syndrome is less clearly defined in terms of the radiation threshold and the mechanism of death, but experiments on animals and a few human radiation accidents show that exposure to 30 to 50 Gy will cause this syndrome. [3]
