This article presents the effects of helmet colors from protective clothing on the thermal protection factor under natural radiation. Thermal exposure distributions were measured using a thermal camera to determine the sun protection effectiveness of helmets under various exposure conditions. Increasing the thermal comfort of the hard hat, which is a work safety protective clothing, has become one of the biggest areas of interest of hard hat designers. Helmets protect human health by providing simple and useful protection against natural radiation rays. To identify the effect of the colors of the helmets, temperature distributions were detected using a thermal camera. White color is important for human health as it has the greatest effect on the thermal protection factor of helmets, which are protective clothing. In this study, recommendations for the engineering of hard hats, which are protective clothing with adequate thermal protection, are presented. Experimental results of white, blue and yellow colored helmets have been determined.

Anahtar Kelimeler

Human health, natural radiation, protective clothing, thermal comfort.

Doğal Radyasyonun Termal Konfor Etkisi: Endüstriyel Baretlerde Renk Faktörü, İnsan Sağlığı

Öz

Bu makale, koruyucu giysilerdeki kask renklerinin doğal radyasyon altında termal koruma faktörü üzerindeki etkilerini sunmaktadır. Kaskların çeşitli maruz kalma koşulları altında güneşten korunma etkinliğini belirlemek için termal maruz kalma dağılımları bir termal kamera kullanılarak ölçülmüştür. İş güvenliği koruyucu giysisi olan baretin termal konforunun arttırılması, baret tasarımcılarının en büyük ilgi alanlarından biri haline gelmiştir. Kasklar doğal radyasyon ışınlarına karşı basit ve kullanışlı koruma sağlayarak insan sağlığını korur. Kaskların renklerinin etkisini belirlemek için termal kamera kullanılarak sıcaklık dağılımları tespit edildi. Beyaz renk, koruyucu giysi olan kaskların termal koruma faktörü üzerinde en büyük etkiye sahip olduğundan insan sağlığı açısından önemlidir. Bu çalışmada yeterli termal korumaya sahip koruyucu giysi olan baretlerin mühendisliğine yönelik öneriler sunulmaktadır. Beyaz, mavi ve sarı renkli kaskların deneysel sonuçları tespit edilmiştir.

Anahtar Kelimeler

İnsan sağlığı, doğal radyasyon, koruyucu giysi, termal konfor.
