Q

addition or removal of an electron with the usual result of ejecting an electron

A

ionization

26
Q

radiation is incapable of ionizing atomic or molecular systems through a single interaction but excites it

A

non-ionizing radiation

27
Q

excitation of atoms produces _

A

heat

28
Q

the effects of radiation are determined on how much radiation was irradiated

A

basis of effect

29
Q

radiation exposure-based symptoms can be evident upon exposure or in a later period of time

A

alarming effect

30
Q

gametes or sex cells

A

germ cells

31
Q

less radiosensitive (recovery)

A

female

32
Q

radiosensitive (recovery)

A

male

33
Q

reproductive organ is _, skin is the only thing protecting it

A

exposed

34
Q

fully matured cells (recovery)

A

most of the cells created by those systems are fully matured high chance of recovery when it exposed to radiation.

35
Q

immature cells (recovery)

A
  • if immature 2 things nothing or higher chance of damage since immature siya di siya nakakapag mature
36
Q

how are specific radiation made

A

energy interaction between atoms. specifically it is formed within the electrons

37
Q

Other radiation?

A

energy can influence matt3er in many ways

38
Q

Radiation not related for diagnosis and
therapeutics?

A
  • Since those radiation are not needed, it is
    better to understand how they are used.
