Discussion, a.

Tbc procedures set forth herein are designed to con *rol the use of radioactive sealed sources used for gar.a radiogrcphy and stowed onboard USS SIERRA (AD-18).

These instructions are based on the 1:nclear Regulatery Ccnission's (hereafter called the '.KC) require ents, and are ca file with the NRC and cust be adhered to without exceptica.

Where questicas arise concerning these rcgulations or an;. questions pertaining to radiation safety, clarification will be obtained from or h the Radiation Safety Officer. /say charge r:ade to enclosure (1) through (14) will be rout ed via the Chain of Cor.and to the 'RC for approval.

a.

Roentren 03.

Unit of exposure of 2 or Crna radiat;r only, Lured by energ; absortion in ni:.

-e b.

Rad.

The unit of absorbed dose.

c.

Absorbed Dose.

Energy per unit cads inparted to natter by loaizing radiation, The unit of absorbed dose is th.- Rad.

d.

1:em.

Undt of dose of ionizing radiation in terms of its biological effects relative to nan, the Ren is the unit of dose for reccrd purposes.

e.

Dose Engivalent.

The dose (in Rads) cultiplied by appropriate twdifying f actors which account for variation in biological effect of varicus types of radiation.

For practical application ene Roentgen of X or Canna radiatien ceasured in air is considered to deliver a dose equivalent of ene Rem to body tissue.

For ::eutron of unknown energy, one Rad is considered to deliver a dose equivalent to 10 Rees to body tissue.

idditionally, for Alpha, one Rad is considered to deliver a dose equivalent to 20 Rems to body tissue.

3.

Dose Ray.

Dose per " nit time.

Co=on units of dose rate are Rem per hour (Renjdr).

Ca ma or X-Ray dose rate is ce=only expressed in Roentgen per 1our (R/ilr) and Milliroentgen per hour (Mr/1!r).

4.

Ixposure Desice.

f.ny equipment used to centain a radioisotope source for the purpose of =aking radiographic exposures.

This is usually a lead or uranium-shielded contair.er.

5.

liigh Radiatica Area. 'Any area accessible to perscanel, in which there exi : s radiation originating in whole or in part from licensed source car. rial at such levels that a ajor portica of the body could receive in any one 'our a dose 2n excess of 100 MR.

The peri =cter on each nigh radiation area chall be calculated and conspicuously posted with a sign or signs bearing the symbol and the words: "CAUTICS - IIIGil RitDI/, TION AREA" 6.

Radiatien Area.

Any area accessible to personnel, in which there exitt radiation. originating in whole or in part frc= licenstd caterial sources, of the body could receive in any one hour at such levels that a por*.A a a does in excess of 5 MR, or in any five (5) consecutive days a doce in excess of 100 '4R.

For the purpost of this intruction the " Radiation Area" will be posted, at the " Restricted Area" 2 MR/liR line, by signs bearing the radiation caution sy-bol and the words:

Transcpidermal inj ury is equivalent to a thermal burn of the second degree blister form.

The blisters aill break open, leaving raw, painful wounds that are very vulnerable to infecticn.

They may occur within ene or two aceks a f ter c>:posurc, depending on the dose received.

The 'et.rns are acccmpanied or preceded by erythema or depilation. Recognizabic injuries of this grade require skin doses in excess of 1,000 Rcn.

The amount of medical care depends on the size and ce'. :rity of the burn.

With hi ;her doses, probably on the order of 5,000 Rem, a care serious version of transepidermal injury eccurs, in %:ich the injury re:;cmbles a scalding or chemical curn.

Pain is prompt and intense.

The raw artc may be very slow in healing or may not heal until sure;ical rescetion and skin grafting is performed.

(d) ?!easurencnts of the level o f circulatinc; blood cells is one of the most useful and simple;t indicators of radiation cffcct.

The fluctuations in the count are the result of chang,es in productica and the destruct 1an rates, as well as ir the life span of the particular cell line.

These levels are associated with varicus degrees of radiation injur; The changes themselves are ncn - spe:itic.

Iloweve r,

when combined with the exposure history or clinical information, they are useful i.ndicate-of radiation overeyr.osure.

Learning Objectives:

Upon successful corpletion of this topic, the worker vill know and understand:

A.

Ilow Douc rate Js reduced by:

1.

The distance fren a radiation source.

2.

The tire that is spent in a field of radiatien.

3.

Shielding the radiatien from tlm cource.

B.

new to calculate stay tine and that, stay tine assists the worker in avoidinr, overe>:posure beyond his permissible 1imits.

II. Presentation:

A.

There are three basic nethods to control exposure to lenizinp, radiation.

They are:

1.

Distance - The farther we are fron a source of radiation, t'..e less exposure we will receive in sonc unit of time.

a.

May be acconplished by:

(?)

predetermine or calculate the radiation field intensity.

This should be acconplished prior to use so as to afford the RitD vorker the greatest distance possible from the source of radiation.

(2) Frequently use survey meters to verify proper calculations.

Tire in a radiation field is the last resort to control a radiatien worker's exposure.

This nethed is used when distance and/or shielding cannot be applied in sufficient quantities.

a.

The time control metbod dees net reduce the dose rate per unit tinc in a radiation field.

b.

The time control r.cthod suggests how long radiation werker may stay in a certain a

radiatien field without exceeding his naxinun pernissible exposure.

c.

Stay-time is the factor used to deternine how lcng a person nay remain on a certain locatien in a radiation field seithout going over his pernissible exposure.

(1)

Stay-tine is important because it is useful to:

(a) Avoid ever-exposure (b)

Determine the length of tine a radiation worker may remain on the job.

(2)

Stay-tine is calculated by the followinp formula:
