INTRODUCTION These specifications are common to all National /Panasonic TL Badges. As for detailed specifications, such a s phosphorous materials and shield combinations, refer.to the

" Specifications for each TL Badge model."

For many measurements and dosage assessment applications, the National /Panasonic TL Badge must be used with a TL Badge Hanger.

As for the National /Panasonic TL Badge Hanger, refer to the

" Specifications common to all TL Badge Hangers" and the

" Specifications for each TL. Badge Hanger model."

1. GENERAL The TL Badge is a thermoluminescence dosimeter for measurement of integral dose of radation.

Elebents-(up to four) are mounted on an element plate..

The element plate is put in the badge holder.

The element-is made of a thin layer of thermoluminescence phosphor. A radiation shield is provided on the badge holder.

An identification number (up to seven digits) is provided on the badge and automatically read by a reader.

The badge is measured without the necessity of taking the element plate out from the badge holder. The element plate is locked to the badge holder to prevent deliberate removal of the plate.

2.1APPEARA:CE At:D CONSTRUCTION Figure 1 (a), (b), (c) shows the appearance of the TL Badge. Depending on the use, three types are available; one-window type, two-window type, and no-window type.

An extremity dosimeter shown in figure 1 (d)~is also available. Forty-bit optical code holes can be made in the badge holder to provide the ID number, etc.

Figure 2 shows the-sectional view and the dimensions of l

the TL Badge. (Though it shows the one-window type

.CD-802A, the figure aisc applies to other types.)

Figure 3 shows the enlarged sectional view of the element.

l Virtually mono-layer of granular phosphor (average granule diameter is 90u) is formed on the thin resin I

substrate. The phosphor is covered with a protective, transparent film.

3. DETAILED COMMON SPECIFICATIONS 7- 1 Thermoluminescence phosphor Depending on specific measurement, four, kinds of phosphor are mounted on the plate in various combinations.

.nt .nB O-(Cu) The phosphor is made of tissue-equivalent Li B 0, with Cu doped as an activator. Natural abundant material nLi and AB is used for Li and B. The phosphor is sensitive to v.x rays and a rays and somewhat sensitive to low-energy neutror.

'Li,"B 0,(Cu) nL i and nB in U Li 2 n s,0jCu) mention-ed above are replaced by enriched material 'Li and "B. The phoschor has l'ittle sensitivit, to neutron rays. The respense to v.x rays and n -

C i 'Li and 5*B. The phosphor has high t

sensitivity to low-energy neutron rays. ,

The response to Y.X rays and 0 rays

! is equivalent to nLi,nB.0,(Cu).

f l CaSO.(Tm) The phosphor is made of non-tissue-j equivalent CaSO. with Tm doped as an activator. Since the phosphor has high sensitivity it is used to evaluate

, low dose in combination with metal shield. Without metal shield, it shows over response to low-energy v.x rays, and is used for energy evaluation of v.x rays. The phosphor has little sensitivity to neutron

It is assumed that the uniformity is evaluated using the reader with rank correction function.

In evaluating uniformity, Class O sometimes shows a percentage standard deviation of 5 to 61 and Class R does 7 to 8% depending on the exposuring method and sampling method.

(1) . A code defining the composition of the element and shield.

l0lll to l1l5l

. Codes from l011l tol1l11 are assigned to standard specification badges and the composition is fixed.

. Codes from l112l toll l4l are assigned to special specification badges and the composition is deter-f mined by the purchaser. (Refer to (iii).)

In this case, the reader parameter must be set according to the badge composition. The badge defining parameter,for the UD-702E manual operation reader cannot be varied.

. Code ll!5! is assigned to the reader calibration badge.

11) A code defining the nominal uniformity class.

(Refer to 3-(7) .)

__ .cperial code When a saecial specification code (betweenIli2!and

!1%!) is assigned to ter.- (1), many TL Badges contain-ing the same model numoer will result. To identify these badges, a serial number is assigned to the badges.

For example, CD-812AQ has many variations: UD-812AQl, CD-812AQ2, ... and incorrect readings will result when CD-612A01 is read by the reader given the badge defining parameters for CC-812A02.

1. General The TL Badge Hanger serves as both a wearing case and as an additive shield for the TL Badge. Except for special cases, TL Badges should be placed in the hanger before being used.

There are three kinds of hangers: an open hanger for single badges, a closed hanger for single budges, and a closed hanger for two badges.

2. Construction The three above hangers are shown in Fig. 1.

A v-G TL Badge is encased in an open hanger, a closed hanger, and also in the right side of the closed hanger for two badges. The hangers are available in several thickness depending en the y-G TL Badges used.

The CD-809A neutron TL Badge is placed in the left side of tha closed two-badge hanger.

The Open hanger has a window for the 8 badge. The closed hanger's eindow is sealed with a 2 mg/cm thick plastic film, T.aning its wall thickness slightly larger for :he G-rays (skin dose) estimating element. The projection shown in Fig. 1 (b) and fc) provides a wall thickness of 1000 mg/cm 2 for the deep dose estimating element.

Closed hangers are designed so that they cannot ce easily cpened withcut special ,i lgs. There is a scace for a .acc.

m ca:t s.;riace.

I

3. Shielding 3-1 Shielding for Y-0 TL Badges The front wall of the hanger is made of plastic.

The thickness of each model is specified in the specifications for each model.

When a TL Badge is encased in a hanger, the total thickness for the Y.x and 5 rays is obtained by adding the hanger thickness to the badge shield thickness. Examples are shown in Appendix 1.

{

I 3-2 The shield for a neutr.on badge 1

i An additional cadmium-made shield for the UD-809A

.eutron badge can be formed on the left side of the closed two-badge hanger.

4. Guarantee This cuarantee is cood for three months from the d. ate of deliverv. This guarantee does not cover problems caused by misuse, abuse, or negligence.

Panasonic will repair or replace, at no charge, your'TL Badge Hanger if any problem develops during the guarantee 7eriod due to design or workmanship defects.
