摘要

本文报道了基于辐射波长为385和395nm的UVA发光二极管(UVA LEDs)的实验台的开发结果，用于对冠状病毒家族病毒(包括SARS-CoV-2)的灭活实验研究。提出了确定在UVA辐射影响下使病毒滴度预先降低的灭活剂量的方法学依据。研究了二极管辐射发散对病毒光灭活过程的影响。结果表明，UVA led可将病毒滴度降低4个数量级。

Inactivation of coronaviruses under irradiation by UVA-range light-emitting diodes

We report the results of the development of an experimental stand based on UVA light-emitting diodes (UVA LEDs) with radiation wavelengths of 385 and 395 nm for studying experimentally the inactivation of viruses of the coronavirus family, including SARS-CoV-2. Methodological grounds are presented for determining the inactivation dose that provides a predetermined decrease in the virus titre under the impact of UVA radiation. The effect of the diode radiation divergence on the virus photoinactivation process is investigated. It is shown that UVA LEDs can be used to reduce the virus titre by 4 orders of magnitude.
