FUN 1 EO: 1.27

1 / 7

Which statement is true regarding stochastic effects?

The severity of the effect increases as the dose increases

The effects typically result from the collective injury of a few cells

They occur by chance and have no established threshold

They have a threshold dose below which no effects will occur

2 / 7

Stochastic effects generally occur without:

Increasing severity with increasing dose

A threshold level of dose

Any chance of occurring with low exposure

Any relation to the dose

3 / 7

What distinguishes non-stochastic (deterministic) effects from stochastic effects?

Non-stochastic effects vary with the dose and have a threshold

Non-stochastic effects always lead to cancer and genetic effects

Non-stochastic effects occur by chance and are independent of the dose

Non-stochastic effects have no chance of occurring below a certain dose

4 / 7

What is a characteristic of stochastic effects related to radiation?

Severity of the effect is proportional to the dose

Severity of the effect decreases as the dose increases

There is a threshold level of dose for the effect

Probability of the effect occurring increases with the dose

5 / 7

Two examples of stochastic effects in the context of radiation protection are:

Skin burns and lowering of blood cell counts

Genetic mutations and cataracts

Cataracts and skin burns

Cancer and genetic mutations

6 / 7

In the context of radiation, which of the following is an example of a non-stochastic effect?

Cancer development

Radiation-induced cataract formation

Genetic mutations

All of the above

7 / 7

What is a common effect that could result from deterministic (non-stochastic) effects due to radiation exposure?

Random occurrence of health issues

Lowering of blood cell counts

Reduction in cancer risk

Increase in genetic mutations
