6) Early researchers working in the field of radiography were not aware that continued exposure
to x-rays produced accumulations of radiation effects in the body because x-rays are invisible.
A) Both the statement and reason are correct and related.
B) Both the statement and reason are correct but not related.
C) The statement is correct, but the reason is not.
D) The statement is not correct, but the reason is correct.
E) Neither the statement nor the reason is correct.
Answer: A
Explanation: A) Because x-rays are invisible, scientists and researchers working in the field of
radiography were not aware that continued exposure produced accumulations of radiation effects
in the body and therefore could be dangerous to both patient and radiographer.
B) Because x-rays are invisible, scientists and researchers working in the field of radiography
