Use the following steps to get a ten-minute average. A ten-minute average is moderately accurate. You can repeat it several times and see how close the averages are. To establish a more accurate average, take a one-hour timed count.
If you need to determine whether there is prior contamination, take averages in several locations and compare the averages.
You can also use Alert mode to warn you if the radiation increases above the alert level. If you suspect an increase in ambient radiation, use the timer to take a five or ten minute count, and compare the average to your average background count.
If you suspect an increase that is too small to detect with a short timed reading, you can take a longer count for example 6, 12, or 24 hours. Checking for Surface Contamination To check a surface, hold the Inspector Alert with the alpha window facing and close to the surface.
If you want to find out if a surface is slightly radioactive, place the Inspector Alert next to it and take a timed count or a longer accumulated count. You may contaminate the instrument. What is radiation? What is background radiation? What are alpha, beta, gamma and X-ray radiation? Marco Kaltofen, PE explains how citizens scientists can properly, collect, document, package and ship radiation samples.
In this video, he also demonstrates how he analyzes radioactive samples in his lab. Arnie Gundersen and Marco Kaltofen talk about how to measure radiation in the environment.

If you change the default image the new one you provide should be 32px by 32px for best results.
The string you pass to change the image URL can be:. The appearance of the alert dialog is controlled by two things: the Skin property of the RadWindowManager , and the values you pass in as arguments to RadAlert. The arguments can include the HTML string you pass in as a message, the width, the height, and the Title string.
The Skin property controls not only the appearance of the popup's title bar, but also the layout of the dialog: its icon, button style, and so on. This dialog layout and appearance is controlled by the alert dialog template associated with the Skin. For details on how to customize the template, see Templates. All Rights Reserved. In Audio mode you will also hear each event. Your ear will be able to detect changes in the count rate as you move closer to, or away from, radioactive sources.
The instrument is calibrated for gamma radiation from Cesium This will give you a relative reading of all radiation combined. Push the Set button to start counting. Counting for long periods, 5 hours or more, will provide best results. Compare total count readings from location to location, or find a stable background level at one location and then compare results with various sources of food or household items. The numeric display shows the current alert level for the current setting.
The radiation symbol and SET icons will also be displayed. The radiation symbol is displayed to show that the instrument is in Alert mode. Radiation levels vary with altitude usually higher as elevation level goes up , and with soil mineral content, and other factors. In an airplane, radiation levels can get quite high due to cosmic rays from outer space that typically are shielded by the upper atmosphere.
Radiation levels on ground at sea level are typically in the range of 10 to 50 CPM, 0. Radioactive materials in the earth, natural or man-made, will contribute to higher levels.
