FUN 1 EO: 1.50

1 / 6

What does the RBE (Relative Biological Effectiveness) quantify in terms of radiation?

The time radiation remains active in an environment

The distance radiation can travel in a given medium

Ability of radiation to cause biological effects like cancer

Ability of radiation to be detected by standard instruments

2 / 6

Why does the Alpha particle cause greater damage if lodged within small essential organs?

The Alpha particle's energy is immediately neutralized

All energy is absorbed in that organ, not spread over larger tissue

The Alpha particle's energy is amplified within larger organs

The Alpha particle will travel through multiple organs

3 / 6

Why does Alpha radiation have a higher RBE value compared to other types of radiation?

Due to the low energy consumption of Alpha particles

Due to the High LET (Linear Energy Transfer) of Alpha interaction

Because Alpha radiation travels further than other radiations

Because Alpha radiation is more easily detected than other radiations

4 / 6

What happens to organ tissue when denser energy is deposited along the path of the Alpha particle interaction?

The organ tissue starts to produce more Alpha particles

The organ tissue becomes more resilient and strong

More damage is found in the organ tissue, cells can be changed or killed

The organ tissue develops a resistance to all types of radiation

5 / 6

How can Alpha contamination ingestion or inhalation particularly affect the human body?

Causes an immediate increase in overall body temperature

Leads to rapid acceleration of hair loss and aging

Leads to immediate external burns and skin irritation

Affects delicate internal workings of lungs or internal organs

6 / 6

How does the RBE value for Alpha radiation compare to Beta-Gamma radiation?

Alpha radiation has an RBE value of 10, Beta-Gamma is 5

Alpha radiation has an RBE value of 1, Beta-Gamma is 20

Alpha radiation has an RBE value of 5, Beta-Gamma is 10

Alpha radiation has an RBE value of 20, Beta-Gamma is 1
