想象一下，一所高中的实验资源非常少，预算有限，甚至无法购买基本的实验室设备。例如，许多高中没有实验研究放射性的手段，因为他们缺乏盖革计数器和/或良好的放射源。这是我们中的一个（MV）工作的第一所高中的情况，在与许多同事交谈后，我们知道许多学校仍然是这种情况。那么，物理教师有什么选择，让他们的学生实验研究放射性的某些特性，如距离如何影响来自放射源的辐射强度？有计算机模拟可以运行，或者也许老师有一个光传感器，并试图根据几何参数在灯泡的光强度和放射源的辐射强度之间进行类比，以获得平方反比定律。但对许多人来说，如果没有盖革计数器和良好的放射性样品，就没有直接的实验选择。正是为了这位老师和这班学生，一个在线的远程放射性实验被创建了。
Imagine a high school with very few experimental resources and limited budgets that prevent the purchase of even basic laboratory equipment. For example, many high schools do not have the means of experimentally studying radioactivity because they lack Geiger counters and/or good radioactive sources. This was the case at the first high school one of us (MV) worked at, and after talking with numerous colleagues we know this is still the case at many schools. What options are there then for physics teachers to allow their students to experimentally investigate certain characteristics of radioactivity, such as how distance affects the intensity of radiation coming from a radioactive source? There are computer simulations that can be run, or perhaps the teacher has a light sensor and tries to make an analogy between the intensity of light from a light bulb and the intensity of radiation from a radioactive source based on geometric arguments to get an inverse-square law. But for many there is no direct experimental option if one does not possess a Geiger counter and good radioactive sample. It is for that teacher and class of students that an online, remote radioactivity experiment was created.
