Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
all of the following statements regarding the somatic effect of radiation are TRUE, EXCEPT
A
x-rays can damage somatic tissues
B
damage caused radiation from somatic effects is passed on to future generations
C
one possible somatic effect of radiation is cancer
D
x-rays affect somatic cells
Explanation: 

Detailed explanation-1: -When ionizing radiation causes DNA damage (mutations) in male or female reproductive (“germ”) cells, that damage can be transmitted to the next generation (F1). This is in contrast to mutations in somatic cells, which are not transmitted.

Detailed explanation-2: -SOMATIC CELL MUTATIONS AND CANCER A long-term somatic effect is the damage to cells that are continually reproducing. These cells are the most sensitive to radiation because any changes made in the parent cell’s chromosome structure will be transmitted to its daughters.

Detailed explanation-3: -Late somatic and genetic effects of radiation can alter the genes in proliferating cells of the body and germ cells. With body cells this may be manifested ultimately as somatic disease such as cancer (leukemia, thyroid, skin, bone), or cataracts.

Detailed explanation-4: -When ionising radiation acts upon gonads or germ cells, it may cause damage to the genetic material (mutations) which can lead to genetically induced diseases (hereditary defects). These may result in malformations, metabolic disorders, immune deficiencies etc.
