What does the Greek word 'soma' mean?

• Mind

• Body

• Cell

• Radiation

What are genetic effects in the context of radiation exposure?

• Effects on the body that was irradiated

• Effects on the future generation resulting from the previous generation's exposure

• Immediate reactions to radiation exposure

• Threshold levels of radiation damage

Somatic effects of radiation are classified as either early or late based on what?

• The severity of the symptoms

• The type of radiation

• The length of time from the moment of exposure to the first appearance of symptoms

• The amount of radiation dose received

What is meant by the term 'threshold' in the context of somatic effects?

• The minimum radiation dose required to cause any biological damage

• The point at which effects begin to appear and below which they are absent

• The maximum safe level of radiation exposure

• The level of radiation that causes immediate symptoms

Which of the following is NOT listed as a possible high radiation dose consequence?

• Nausea

• Blood disorders

• Increased sperm count in male

• Injury to the central nervous system

What is Acute Radiation Syndrome also known as?

• Acute radiation sickness

• Hematopoietic syndrome

• Gastrointestinal syndrome

• Cerebrovascular syndrome

At what whole-body dose of radiation does Hematopoietic syndrome occur?

• 1-10 Gy

• 2-10 Gy

• 6-8 weeks

• 3-10 days

What is the primary effect of Hematopoietic syndrome on the body?

• It destroys bone marrow.

• It increases survival time.

• It causes death within 3-10 days.

• It leads to the latent stage of gastrointestinal syndrome.

What is the survival time for people with Hematopoietic syndrome as the radiation dose increases?

• Survival time increases.

• Survival time does not change.

• Survival time shortens.

• Survival time is about 3 weeks to 6 months.

At what dose of radiation does Gastrointestinal syndrome typically occur?

• After a dose of 1-2 Gy

• At a threshold dose of 6 Gy and peaks after a dose of 10 Gy

• For doses from 2-10 Gy

• For an exposure just about 2 Gy
