TEST REPORT

NO. 960840750-1 of 05 APRIL 2006

 

 

 

Alpha-Beta-Gamma (α-β-γ) RESIDUAL RADIOACTIVITY TEST

 

 

MATERIAL TESTED:

 

Kryptaglow Luminescent Paint Layer on Cement Substrate identified by Co-Leash Inc. as consisting of three coats:

(i) Kryptaglow White Latex Base Coat # 1171, (ii) Kryptaglow Paint MEA Special Blend # 1300A, and (iii) Kryptaglow

Clear Protective Top Coat # 1102, and listed in this test as Material A.

 

TEST RESULTS:

 

1. NO INTEGRAL ALPHA, BETA AND /OR GAMMA (Α, Β AND/OR Γ) RADIATION ABOVE

THE BACKGROUND NOISE RADIATION LEVEL.

 

2. THE SAMPLES OF MATERIAL A ARE NON-RADIOACTIVE AS TESTED TO NYC BC

REF. STD. 6-1, para. 4.1 to 4.4, and ASTM D3684.

 

 

TEST DESCRIPTION

 

1. The test per NYC BC Ref. Std. 6-1 and 6-1A and ASTM 3648. Test conditions: T=22°C, RH=40%, P=101.2 kPa.

 

2. The radiation intensity readings were taken at nine different points on the surface of each of the three specimens of each

of the two materials tested, both inside and outside of the radiation insulating chamber and under twelve angles between

the normal to the sample surface and the direction of the field of gravity. The radiation intensity reading for each of the

test runs shows only the magnitude of the background radiation noise.

 

3. The experimental error evaluated by the partial derivatives and least squares methods does not exceed 6%. The data on the standard

deviation are kept on file at CIEMS.

 

4. INSTRUMENTS AND DEVICES USED

- Geiger Counter Model SGM-49C PRI (2.5 µR/hr per div.)

- Nuclear Radiation Monitor Model DX-1 ITS (1 µSv/h per div.)

- Scintillation Counter Model 111 PRI (0.5 µR/hr per div.)

- Survey RA Instrument Model HP-370 Eberline with α-β-γ Proportional Counter Model 4314 LND

- Envirothermocryostat Model 510 GRE with Programmed Temperature/Humidity Controller and Lead-Clad Compartment Model

100B CII

- Digital Hydrothermometer Model 63-844 MI, Barometer Model 602650 SB

- Starrett Dial Indicator Model 25-109 (1.270 µm/div.).

 

5. The standard reference materials used for the test setup calibration:

- NIST SRM 4320 (Cm-244)

- NIST SRM 4326 (Po-209)

 

6. The equipment used in the test meets the applicable NIST, ASTM, ASME, OSHA and State requirements and was calibrated with the

standards traceable to the NIST. The calibration was performed per ANSI/ISO/ASQ Q9004-2000, ANSI/ASQC M1-1996, ISO

10012:2003, MIL-STD-45662, MIL-I-45208, NAVAIR-17-35-MTL-1, CSP-1/03-93 and the instruments manufacturers' specifications.

 

7. The equipment passed a periodic accuracy test in June 2005. Next test - June 2006. The linear and angular measure equipment and

weights were calibrated in December 2005.
