Internal exposure occurs when a radioactive material is ingested or works its
way inside the body through an open wound. This can cause alpha particles,
beta particles, neutrons and gamma radiation to be present inside the body.
The person will then be radioactive
Choose an answer
1 What is Radiation 2 What are some acute effects
3 Whats an internal exposure 4 Curie disintegrations per second
Don't know?
Terms in this set (109)
, A process in which particles travel through a medium
What is Radiation
or a space
the time taken for the radioactivity of a specified
What is half life
isotope to fall to half its original value.
a positively charged atom and its corresponding
What is an ion pair
displaced negative electron
How is an isotope made Fission or Altering the N/Z ratio
Curie disintegrations per 3.7x10^10
second
Specific activity is the degree of concentration of
radioactive material within the radioactive source and
What is specific activity
is expressed as becquerels per gram or curies per
gram
What is characteristic a measure of the ionization of air it produces.
intensity
What is radiographic density difference between two areas on a radiograph
contrast
What is radiographic the abruptness of change in going from one area of a
definition given radiographic density to another
EX of natural radiation Cosmic rays , elements from earths crust
Internal exposure occurs when a radioactive material
is ingested or works its way inside the body through
Whats an internal
an open wound. This can cause alpha particles, beta
exposure
particles, neutrons and gamma radiation to be present
inside the body. The person will then be radioactive
External exposure comes from the body being
exposed to a source of radiation that is located
Whats an external outside the body such as ultraviolet, x-rays or gamma
exposure radiation. Once the source of radiation is removed,
there is no sign of radioactivity from the person
affected
