The biological damage caused by 1 gray -radiation is compared with 1 gray -radiation in the same type of human tissue. The damage caused by the -radiation is
Options
- Amore serious as compared to the damage caused by the -radiation.
- Bless serious as compared to the damage caused by the -radiation
- Cequally serious as the damage caused by the -radiation
- Dincomparable with the damage caused by the -radiation, because -radiation are not particles.
Correct answer
B. less serious as compared to the damage caused by the -radiation
Step-by-step solution
The damage caused by the -radiation is less serious as compared to damage caused by the -radiation. This is because -radiation is more dangerous than beta or gamma if ingested because its power to ionize or to disrupt, atoms is 20 times more than and . But if the source is outside the body or at a distance gamma radiation is much dangerous because it could penertrate thick walls of skin.
