The latest version of the Digilert 200 requires that the timer be set prior to accumulating total count. To take a timed count, follow these steps: 1. With the Digilert200 operating, set the Mode switch to Total. The display shows 0 and Total in the upper left portion of the display. 2. Press the SET button on the end panel to set the time for your count. You will see the hourglass, and the most recent timing period used. The first time you use the timer, the setting is 00:10 (ten minutes). 3. Use the + and - buttons to set the timing period. The timed period can be for 1 to 10 minutes in 1-minute increments, for 10 to 110 minutes in 10-minute increments, or for 2 to 24 hours in 1 hour increments. 4. Press the SET button. The Digilert200 starts totaling the counts it registers, and the numeric display is updated each time a count is registered. The hourglass indicator flashes during the timed period. During the counting period, if you want to see how many minutes remain, press and briefly hold the SET button. The display counts down from the time setting in hours and minutes to zero. For example, if the display shows 00:21, then 21 minutes remain. 5. At the end of the timed period, the Digilert200 beeps 3 times and repeats the beeping 3 times. The number displayed is the total count and the hourglass will stop flashing and remain solid. 6. To find the average dose rate for the timed period, divide the total by the number of minutes. The average count is in counts per minute. To convert to mR/hr for Cesium-137, divide by 1070. 7. Move the Mode switch to one of the dose rate modes to return to normal operation. If you move the Mode switch to one of the dose rate modes while the Digilert200 is taking a timed count, the timed count will continue. 8. To reset the timer to take another timed count, press the SET button to set the time for another count. 9. Press the SET button a second time and the Digilert200 will start totaling the counts it registers, and the numeric display is updated each time a count is registered.

The six samples in our NORM (Naturally Occurring Radioactive Material) Student Kit contain tiny quantities of radioactive material obtainable commercially by anyone who wants to purchase them. No radioactive material license is required to possess or transport them. The quantities are individually and collectively well below the IATA Activity Limit for an Exempt Consignment (from IATA Dangerous Goods Regulations Table 10.3.A) and U.S. Department of Transportation regulations 49 CFR 173.436). No shipping label of any kind is required, no Declaration for Dangerous Goods, and no packaging requirements are specified.

The RAD-60 is basically a stand-alone dosimeter and no other options are required for it's use. The RAD-60 comes with user selectable settings. There are 6 pre-set alarm levels to choose from for both dose and dose rate. Those levels are: 1,10,100 mrem and 1, 10 and 100 Rem. The same goes for Dose Rate; 1,10 and 100 mrem/h and 1,10,100 Rem/h. The user can enhance the experience with several options with which to choose. Two of those are available software packages. With the ADR-1 Configuration Kit, a user can assign names and ID numbers to a dosimeter; change dose and dose alarm levels to other than the 1, 10 and 100 settings, for example, to 25 mrem if they wish. In addition, the Kit can be used to change Chirper level settings, initiate the Timer function or to perform calibrations. It can also be used to disable button functions if so desired so that the user cannot clear their own dose for example. In contrast, the ACS X-Press Software is a Database SW used to track dosimeter inventory and personnel dose records. You can log in/out, enter tasks etc. The Software provides reports of dose exposure and dose history for persons. The X-Press Software can be used with or without a reader but a reader is recommended for a controlled situation.
