Instructor Guide - pg v,

Change "ACCIDENTAL DOSES" to "ACCIDENTAL EXPOSURES".

Module 101, H

Change "accidental doses" to "accidental exposures".

Instructor Guide - pg 3,

Instructor Guide - pg 9

Change "Rad, a measure of the energy absorbed per unit mass."

To "Rad, a measure of the energy absorbed per unit mass.

It is defined for any absorbing material."

Instructor Guide - pg 13

Change " ACCIDENTAL DOSES" to "ACCIDENTAL EXPOSURES"

Change "(3.5 X 10 -4) x Z x E" to "(7 X 10 -4) x Z x E"

Instructor Guide - pg 25

Change "(3.5 X 10 -4) x 74 x 0.150 = 0.004" to "(7 X 10 -4) x 74 x 0.150 = 0.008"

"Then the energy transformed into X-rays would be 0.004 [7500] = 30 J/s.

1 J = 107 ergs, and 100 ergs/g = 1 rad.

So this X-ray energy represents:

30 x 108 ergs/sec.

If all this X-ray energy were deposited in 1 g of tissue, the dose would be:

3.0 x 108 ergs/sec [1 rad/100ergs/g] =

3.0 x 106 rad/sec."

To -

"Then the energy transformed into X-rays would be 0.008 [7500] = 60 J/s.

1 J = 107 ergs, and 100 ergs/g = 1 rad.

So this X-ray energy represents:

6.0 x 108 ergs/sec.

If all this X-ray energy were deposited in 1 g of tissue, the dose would be:

6.0 x 108 ergs/sec [1 rad/100ergs/g] =

6.0 x 106 rad/sec."
