Abstract :

<p>&nbsp;The most common therapeutic intervention used for the treatment of hyperbilirubinemia is phototherapy. The effectiveness of neonatal hyperbilirubinaemia treatment depends directly on the exposure to blue light (&lambda; &asymp; 450 nm) expressed by irradiance in W/m2. To assess the efficacy of the light source, a radiometric method was setup to ensure the competence of phototherapy devices (luminaire) to the standard international and national requirements. In this work, nine types based on fluorescent lamps which found to provide a uniformity higher than the minimum standards requirements (0.45 &ndash; 0.75), and four types based on Light Emitting Diodes (LEDs) phototherapy devices provide a uniformity (0.05 &ndash; 0.42). While as the irradiance levels obtained from lamps (Ë&sbquo; 8 &ndash; 26.7 &micro;W/cm2/ nm) and (33.3 &ndash; 122.2 &micro;W/cm2/nm) from LEDs. Hence, NIS provides traceability to customer through unoken chain of phototherapy radiometer caliated as irradiance response in W/m2. Uncertainty model includes (caliation of the reference detector, distance effect, drift of the caliation, repeatability, and the resolution of the measuring device) are studied.</p>
