Important Information
All radioactive devices using Polonium-210 are leased for one (1) year. It is important to keep
track of these units so that they can be returned to NRD for proper disposal. If the device is
misplaced, please call NRD for information on how to report the lost device.
2.1
Safety of NRD Ionizers
The radioactive material (Polonium-210) is 100% encapsulated using a pressure welded
metallurgy technique. The result is an encapsulation that is insoluble and inert to most
chemicals. Vibration and impact normal to industrial applications will not adversely affect
product integrity.
The alpha particles come from the natural decay of the radioactive source and collide with air
molecules to create ions. However, alpha particles are unable to penetrate a thin piece of paper
or human skin! Complete safety is ensured when the ionizers are used in accordance with
normal mounting and operating conditions. Normal use and conditions of the ionizer include:
•
Temperature not to exceed 212° F (100° C).
•
Use air, nitrogen or an inert gas.
•
You can safely handle the outside of cell. Do not insert any object or attempt to clean
the inside of the cell.
•
Mount the ion cell in a normal way by using the mounting posts of the ion cell. Do
not alter the ionizer in any way, i.e. drilling holes. Contact us for mounting options.
Review the enclosed
Safety Brochure
for a more detailed description of how the ionizers work,
where they are typically used, and the general safety of NRD ionizers.
2.2
Lease Agreement
All ionizers containing Polonium-210 are leased, not purchased. The devices are leased for two
main reasons: 1.) Federal Regulations state that the device must be tested for radiation leakage
prior to shipping and before 13 months from the date of manufacture. NRD performs these leak
tests and provides you with a Leak Test Certificate as documentation. 2.) The activity of the ion
cell decreases over time. At the end of 12 months, the cell needs to be replaced (or renewed) in
order to maintain its effectiveness.
NRD will notify you when it is time to renew the device. To renew the lease when the device
reaches its 12 month expiration (the manufactured date is printed on the label of device), simply
provide us with a new purchase order to make the original lease valid for another 12 months.
Upon delivery of the renewed device, remove the old cell from service and ship it back in
accordance with the
Return Shipping Instructions
.
