they are immature, undifferentiated, and rapidly dividing

The latent period in radiation biology is the time between: - Answer ✔ exposure to x-
radiation and clinical symptoms

Acute Radiation Syndrome (ARS) - Answer ✔ Symptoms of short term radiation effects
after a massive dose of ionizing radiation

Long-term effects of radiation - Answer ✔ Cancer, embryological defects, genetic
mutations, life-span shortens

contained in the DNA; may be passed to the next generation

What are the sources of exposure? - Answer ✔ X-rays (external) and radionuclides
(internal)

Filtration
Collimating

MAS is adjusted to control the: - Answer ✔ amount of x-rays produced

X-ray contrast studies of certain joints , such as the knee and shoulder, are called: -
Answer ✔ Arthograms

Density of the radiograph is a function of: - Answer ✔ the kilovoltage applied, the
milliamperage, the time of exposure
