FUN 1 EO: 1.38

1 / 7

What does the method in Section 3.0 of ANSI/HPS N13.41-1997 provide?

A method for calculating the exact dose to the skin

A method for calculating internal dose from external sources

A method for measuring radiation exposure to the eyes

A method for estimating the EDEX from several dosimeter results

2 / 7

In extremely non-uniform irradiations, using the DDE measured at the highest exposed part of the whole body as the EDEX can be considered what?

Partially moderate

Completely accurate

Highly liberal

Overly conservative

3 / 7

In 10 CFR Part 20, the EDE is defined as the sum of products of dose equivalent to each organ or tissue (ΗT) and what other factor?

The energy level impacting each body organ or tissue

The weighting factors (WT) applicable to each body organ or tissue

The exposure time for each body organ or tissue

The radiation type affecting each body organ or tissue

4 / 7

What are the two components that 10 CFR Part 20 breaks the TEDE into for the purpose of implementing workplace controls?

Dose resulting from long-term and short-term exposure

Dose resulting from alpha and beta radiation

Dose resulting from natural and artificial sources

Dose resulting from radioactive sources internal and external to the body

5 / 7

What are the non-TEDE dose limits that 10 CFR 20.1201(a) and 10 CFR 20.1201(c) require to be measured at specific body locations?

Dose to the head and neck, dose to the upper arms, dose to the thighs

Dose to the lungs, dose to the heart, dose to the lower abdomen

Dose to the lens of the eye, dose to the skin of the whole body and extremities, or the total organ dose

Dose to the internal organs, dose to the external skin, dose to the brain

6 / 7

Which part of the body is given a compartment factor (WC) of 0.50 in Table 1 for estimating the EDEX?

Head and neck

Thorax, above the diaphragm

Abdomen, including the pelvis

Right thigh

7 / 7

When the body is not irradiated uniformly, why does a single-dose measurement not determine the accurate EDEX?

It only measures the dose to a specific organ or tissue

It does not account for the age of the person being measured

It measures only the external dose to the body

It cannot determine the dose to the various organs and tissues
