摘　　要：本文介绍电子辐射对不同墨水书写信息的影响。2001年10月当发现炭疽病毒感染邮寄的信件时,美国政府开始利用电子辐射杀死邮件上的病毒,并在全国推广这项技术。可是过了一段时间发现,这项技术对某些邮寄物品是有害的。数据表明电子辐射可能对邮品上存在的时间特征有损害,尤其是邮寄通过常规船运的美术和历史资料,时间特征是非常重要的。The effect of electron beam irradiation on a series of different writing inks is described. As the anthrax-tainted letters were discovered in October 2001, the U. S government began to experiment with the use of the electron beam irradiation process for destroying such biological agents. Plans initially considered a large-scale countrywide use of this technology. However, over time the scope of this plan as well as the radiation dosage were reduced, especially when some adverse consequences to mailed items subjected to this process were observed. Data existed at time to characterize what level of damage might be expected to occur with common items sent through the mail. This was especially important to museums and other institutions that routinely ship valuable and historic items through the mail.
