【摘要】：光生物學(xué)是研究光輻射與生物器官組織相互作用的學(xué)科。光生物安全主要研究的是光輻射對人體的眼睛和皮膚的輻射危害性，并對各種人造光源給出安全性評價和使用建議，，提高公眾對光輻射的防護(hù)意識。由于光生物安全領(lǐng)域中測量的特殊性和復(fù)雜性，到現(xiàn)在為止我國還沒有建立相應(yīng)的光生物安全計量標(biāo)準(zhǔn)以及相應(yīng)的量值溯源系統(tǒng)。本論文主要研究光生物安全計量標(biāo)準(zhǔn)與測量方法，建立光輻射曝輻量的測量裝置與量值溯源系統(tǒng)，主要內(nèi)容和研究成果如下： (1)對光生物安全領(lǐng)域的國內(nèi)外標(biāo)準(zhǔn)和研究情況進(jìn)行了文獻(xiàn)調(diào)研和綜合評述，詳細(xì)比較了不同標(biāo)準(zhǔn)之間的差異。 (2)研究了光生物安全測量系統(tǒng)的量值溯源涉及到的光譜輻射照度標(biāo)準(zhǔn)燈模型，包括高溫黑體到光譜輻射照度標(biāo)準(zhǔn)燈的量值傳遞以及光譜輻射照度標(biāo)準(zhǔn)燈到光生物安全測量系統(tǒng)的量值傳遞。根據(jù)人工神經(jīng)網(wǎng)絡(luò)具有良好的非線性映射及泛化能力，提出了光譜輻射照度標(biāo)準(zhǔn)燈的RBF神經(jīng)網(wǎng)絡(luò)模型，旨在減小量值傳遞過程中的不確定度，并與普朗克-多項式模型進(jìn)行比較，證明了RBF神經(jīng)網(wǎng)絡(luò)模型的優(yōu)越性。 (3)建立了光生物安全測量裝置與量值溯源系統(tǒng)。包括加權(quán)輻射照度、空間平均輻射亮度和表觀源測量裝置，并對測量裝置的性能指標(biāo)，如波長準(zhǔn)確度、測量重復(fù)性等進(jìn)行了測試。 (4)介紹了輻射危害風(fēng)險等級類型和危害距離信息的分析方法，提出了基于輻射照度計確定光源的危害距離的簡化方法，并通過實驗對方法進(jìn)行驗證。對臺燈、紫外光源、手機(jī)閃光燈等樣品進(jìn)行了光生物安全測試，給出了其輻射危害風(fēng)險等級分類和危害距離信息，為其安全使用提供指導(dǎo)。
[Abstract]:Photobiology is the study of the interaction between light radiation and biological organs and tissues. Photobiosafety is mainly concerned with the radiation harmfulness of light radiation to human eyes and skin, and gives safety evaluation and application suggestions for various artificial light sources. To raise public awareness of the protection of light radiation. Due to the particularity and complexity of measurement in the field of photobiosafety, Up to now, our country has not established the corresponding photobiosafety metrology standard and the corresponding quantity traceability system. This thesis mainly studies the photobiosafety measurement standard and the measurement method. The measurement device and traceability system of radiation exposure are established. The main contents and research results are as follows:. 1) the domestic and international standards and research situation in the field of photobiosafety are investigated and reviewed, and the differences among different standards are compared in detail. (2) the spectral radiance standard lamp model related to the traceability of photobiosafety measurement system is studied. It includes the quantity transfer from high temperature blackbody to spectral radiance standard lamp and from spectral illuminance standard lamp to photobiosafety measurement system. According to the artificial neural network, it has good nonlinear mapping and generalization ability. The RBF neural network model of spectral illuminance standard lamp is proposed, which aims to reduce the uncertainty in the process of value transfer. Compared with Planck-polynomial model, the superiority of RBF neural network model is proved. A photobiosafety measuring device and a traceability system are established, including weighted radiance, spatial average radiance and apparent source measurement, and the performance of the measuring device, such as wavelength accuracy. The repeatability of measurement was tested. (4) this paper introduces the analysis method of risk level and hazard distance information of radiation hazard, puts forward a simplified method to determine the harm distance of light source based on radiometer, and verifies the method by experiment. The photobiosafety test of mobile phone flash lamp was carried out, and the classification of radiation hazard risk and the information of hazard distance were given, which provided guidance for its safe use.
