The effects of radiation on biologic material depend on several factors. If a large quantity of radiation is delivered to a body over a short period of time, the effect

A. will be greater than if it were delivered in increments

B. will be less than if it were delivered in increments

C. has no relation to how it is delivered in time

D. solely depends on the radiation quality

Answer: B. will be less than if it is delivered all at one time.

Explanation:

The biological effects of radiation can be divided into two categories. The first includes the exposure of the biological material to high doses of radiation for short period and the effects are acute or for the short term.

The second includes exposure of radiation of low dose over an extended period that produces chronic or long term effects.

High doses of radiation when exposing for a short period can produce acute or short term effects.

Low doses of radiation when expose for a long period can cause immediate health effects or chronic diseases.

According to the given situation, if the large quantities of radiation are given to the body for a short period the effect will be less then if delivered for a long period.
