1 March 2006 Berkeley Nucleonics Corporation How to Use the palmRAD 907

2 March 2006Berkeley Nucleonics Corporation This presentation is intended to give the user a brief overview of how to operate the palmRAD 907. For a complete understanding of this instrument please refer to the operating manual.

3 March 2006Berkeley Nucleonics Corporation What the palmRAD 907 Does The palmRAD 907 measures the rate of the following types of nuclear radiation The palmRAD 907 measures the rate of the following types of nuclear radiation Alpha Alpha Beta Beta Gamma Gamma X-radiation X-radiation The palmRAD 907 measures the amount of nuclear radiation in The palmRAD 907 measures the amount of nuclear radiation in Counts per minute (CPM) Counts per minute (CPM) Counts per second (CPS) Counts per second (CPS) MilliRoentgens per hour (mR/hr) MilliRoentgens per hour (mR/hr) MicroSeiverts per hour MicroSeiverts per hour (µSv/hr) (µSv/hr)

4 March 2006Berkeley Nucleonics Corporation How to Turn On the palmRAD 907 Turn the palmRAD 907 on by moving the lower switch from to or. Turn the palmRAD 907 on by moving the lower switch from Off to On or Audio. --The palmRAD 907 is measuring radiation but there is no audio. On--The palmRAD 907 is measuring radiation but there is no audio. --The palmRAD 907 is measuring radiation, and beeping with each count of radiation that is detected. Audio--The palmRAD 907 is measuring radiation, and beeping with each count of radiation that is detected. When the palmRAD 907 is first turned on it does a 3 second system check, displaying all the indicators and numbers. When the palmRAD 907 is first turned on it does a 3 second system check, displaying all the indicators and numbers. After the system check is finished the palmRAD 907 shows the current level of nuclear radiation. After the system check is finished the palmRAD 907 shows the current level of nuclear radiation. The palmRAD 907 updates its visual display once every three seconds. The palmRAD 907 updates its visual display once every three seconds.

5 March 2006Berkeley Nucleonics Corporation How to Select the Operating Mode Move the upper switch to Move the upper switch to Total/Timer (counts per minute or counts per second) CPM/CPS (counts per minute or counts per second) or (milliRoentgen per hour or microSeivert per hour). mR/hr or µSv/hr (milliRoentgen per hour or microSeivert per hour). In mode the palmRAD 907 starts totaling the counts it registers, and the numeric display is updated each time a count is registered. In Total mode the palmRAD 907 starts totaling the counts it registers, and the numeric display is updated each time a count is registered. The mode is the easiest to understand for the layperson. The CPM mode is the easiest to understand for the layperson.

6 March 2006Berkeley Nucleonics Corporation How to Switch the Mode To switch the mode from to and from to : To switch the mode from mR/hr to µSv/hr and from CPM to CPS: Turn the palmRAD 907 off. Turn the palmRAD 907 off. Hold down the button on the end panel while turning the palmRAD 907 on. Hold down the + button on the end panel while turning the palmRAD 907 on. Scroll through the numbers on the screen until you get to. Scroll through the numbers on the screen until you get to 2. Press the button on the end panel. Press the SET button on the end panel. Use the or button on the end panel to toggle between settings. Use the + or - button on the end panel to toggle between settings.

7 March 2006Berkeley Nucleonics Corporation What is Background Count? The background count is the normal level of nuclear radiation that is occurring at a given time and place. The background count is the normal level of nuclear radiation that is occurring at a given time and place. Some sources of background radiation are: Some sources of background radiation are: The sun The sun Minerals in the earth Minerals in the earth Residual radiation from nuclear testing and other man made sources Residual radiation from nuclear testing and other man made sources Nuclear radiation is a naturally occurring phenomenon. When the palmRAD 907 is on it is normally measuring the background count. Nuclear radiation is a naturally occurring phenomenon. When the palmRAD 907 is on it is normally measuring the background count. A user should determine the normal background count in case abnormal levels of nuclear radiation occur. A user should determine the normal background count in case abnormal levels of nuclear radiation occur. The mesh screen covers the end window of the Geiger-Mueller sensor.

8 March 2006Berkeley Nucleonics Corporation How to Determine the Average Background Count Turn the palmRAD 907, and put it in Total mode. Turn the palmRAD 907 On, and put it in Total mode. Set the switch on the end panel to. Set the Timer switch on the end panel to Set. Press the button until the display reads 00:10 (this means ten minutes). Press the + button until the display reads 00:10 (this means ten minutes). Set the switch to. The palmRAD 907 beeps three times and starts counting. Set the Timer switch to On. The palmRAD 907 beeps three times and starts counting. At the end of the ten minutes, the palmRAD 907 beeps three times, and repeats beeping several times. Note the total reading. At the end of the ten minutes, the palmRAD 907 beeps three times, and repeats beeping several times. Note the total reading. Divide this number by ten for the average count per minute which is the average background count per minute. Divide this number by ten for the average count per minute which is the average background count per minute.

9 March 2006Berkeley Nucleonics Corporation How to Change the Battery Turn the palmRAD 907 over. Turn the palmRAD 907 over. Remove the battery cover. Remove the battery cover. Detach the 9 volt battery from the wire connector and replace. Detach the 9 volt battery from the wire connector and replace. The battery life for the palmRAD 907 is approximately 200 hours. The battery life for the palmRAD 907 is approximately 200 hours.
