Quiz zum Vortrag
A pregnant female undergoes multiple abdominal CT scans for extensive trauma at a gestational age of 30 weeks. The child from that pregnancy develops leukemia at the age of 8. Which of the following statements is TRUE?
- If the leukemia is related to radiation exposure, this would be a stochastic effect.
- If the leukemia is related to radiation exposure, this would be a deterministic effect.
- The leukemia is linked to radiation exposure.
- The leukemia is not related to radiation exposure since the exposure occurred at a late gestational age.
- The mother should not have undergone any imaging due to the possibility of radiation effects on the fetus.
What type of radiation is deflected in a different direction and is neither absorbed nor transmitted to the detector?
- Scatter
- Absorbed
- Transmitted
- Resorbed
- Deflected
Which of the following is NOT a source of radiation?
- Ultrasound
- Cosmic radiation
- X-ray
- Soil
- Radon
Which of the following is a feature of deterministic effects of radiation?
- It results in skin erythema, cataract and sterility.
- It is dose independent.
- Increasing the dose increases the probability of its biological effect.
- There is no set threshold dose for the effect to occur.
- It can lead to the development of cancers.
A 28-year-old woman recently discovered she was pregnant. If she has a radiation exposure of more than 10mGy on the 10th day of conception, what is the probable effect on the fetus?
- Fetal demise
- Microcephaly
- Mental retardation
- Childhood malignancies
- Urinary tract anomalies
Which among the following is NOT implemented for radiation protection?
- Use lead shielding for the family member of radiologists and technologists to prevent transmitting radiation.
- Follow ALARA - as low as reasonably achievable.
- All radiologists and technologists must be monitored by a film badge which shows the amount of radiation that the person is receiving.
- Use lead shields during the exposures.
- Design rooms with shields.
