(This mini-graph updated Tue Jul 29 16:30:30 2014 East Coast US time)
A real-time mini-graph generated by Aware's Aw-graph program displaying
nuclear flea level (Radon decay products) in southeastern Pennsylvania. (See Latest Data graph below). Aw-graph plots not
only radioactivity but any ascii data. Resize with an easy to use zoom
box. These make great real-time scrolling mini-graphs in a small
window. We've added a gif dump function to Aw-graph
program for easy (even automatic) placement of graphs on the Internet.
Shown to the left is Aware's LCD-90 and RM-80. A Class 1 Bluetooth Adapter with built-in rechargable Lithium Ion battery is plugged into the LCD-90's serial port, feeding real-time data wirelessly to Aw-Radw seen in the background.
They provide an interesting powerful and easy method of detecting and
plotting ionizing radiation on a P.C. or LAPTOP computer. No need for
batteries or external transformers. An efficient regulated power supply
draws a minute amount of power from the computer port. Each monitor is
extremely rugged and accurate. Many thousands have been sold since 1989
and the first are working as new.
Excellent for educational and industrial purposes as well as for checking minuscule amounts of contamination in foods, water, ceramic materials and more or for continuously monitoring background radiation levels including radiation due to the presence of Radon and decay products.

"Does this prove that Port Chicago was a nuclear accident? No. It confirms only that there's higher than normal background radiation in the places where it was measured":
Please Note: In the interest of variety, as of Aug. 31st 1998 11:00 pm we switched from a RM-60 + Fan-Filter to a RM-80 + Fan-Filter for the real time graphs on this web site. We also moved the sensor to the basement area as opposed to the living room area. See the next graph on this page for the latest RM-80 data.

The count rate is in direct correlation with Alpha and Beta particle
flux. The radioactivity of the filter is in direct correlation with
what is going on in the lungs of any person breathing the same air as is
passing through the filter. In many respects this information is much
more useful for the user as compared to a Radon report in the form of
picocuries Radon per liter air. For example a forced air filter system
could remove a large percentage of Radon decay products from the air
thereby reducing the health threat but the filter system would not
remove any Radon gas and therefore a standard Radon test would show no
reduction in Radon level even though the health threat was greatly
reduced. Never-the-less the counts per unit time figure included in
these graphs can be converted to picocuries Radon per liter air given
the correct factor. For more info about monitoring and reducing Radon decay
products see: Frequently asked questions

The software included with each RM is very user friendly and non-intrusive to your PC environment. You can even run it from your floppy. Setup is easy. Simply plug the adapter into a serial port and start the software. It makes for a very interesting PC application.
The RM-60 along with the user friendly software ($179.95 complete system) monitors and plots radiation from a variety of sources. It includes the highest quality stainless steel geiger tube with alpha-beta window and ceramic back. The RM-60 detects all three types of radiation emitted by radioactive materials namely Alpha, Beta, and Gamma radiation as well as X-ray radiation down to 8 KEV (8K Electron Volts).
The RM-70 ($289) and RM-80 ($329) monitors include the highest quality, industry standard stainless steel "pancake" tubes (1.125" and 1.75" effective diameter Alpha, Beta, low energy Gamma, X-ray windows). The RM-G90 ($523) includes a 10.5" x 0.8" stainless steel gamma tube (160 cps/milliR/hr). (For more technical specs. click on "RM specs" link above).
The monitors plug into the serial or parallel port of the P.C. by way of telephone cord turning the computer into a highly sensitive feature packed user friendly microroentgen geiger counter. Data is displayed in a unique scrolling bar chart format and is saved to a file for later review and manipulation. Each point is accompanied by the exact date and time according to the quartz clock in the computer.
You can use a credit card to order if you desire. If you are displeased for any reason you may return the unit within 45 days for a full refund. (For more order info. click on Price List link above).
If you decide to order may we suggest the purchase of the additional
program Aw-graph.exe for $74.00 or our 32 bit Windows program Aw-Radw which includes Aw-Graph.

Both include the ability to view several radiation data files
simultaneously including regressions, interpolations, semi-log plots,
background subtraction, date-time x-axis, data compression, flash -
video page switching and more. Included are real-time automatic updates
of data plot(s) as well as old data and/or any ascii data. Aw-graph and
Aw-Radw are covered by the 45 day $ back offer. Either are superb add-on
programs.
Note: Several utilities are included with each RM system. These include SEED.EXE which generates random numbers derived from RM pulses (Also see:NEW PROGRAM: AW-RAND random number generator), SECTION.EXE which pulls any Date-Time data segment from a large data file, SETCLOCK.EXE which uses a modem to connect with Atomic Clock in Boulder Colorado, then adjusts PC's clock, Flux Counter, which tallies radiation counts until space-bar is pushed, Stufkbuf.exe which places keystrokes in the keyboard buffer and more.
RADON:
Even in a room with only outdoor Radon levels one can gather Radon
decay products on a tissue by wiping the screen of a VGA or T.V. and
then plot the decay with an Aware monitor and the software. (Half-life
Radium B: 26.8 mins., Radium C: 19.9 mins.) Use one of the RM monitors
to find Radon entrance points. For example if Radon is entering
through a crack, daughter products will deposit around the periphery of
the crack. When moving the monitor close to the crack, geiger clicking
will increase and the dose rate display will show a rise in radiation
due to the highly radioactive decay products. This reveals the crack as
a source of Radon entrance.
We received an interesting phone call from a RM-60 user. He has been an
Alpha track dealer for several years and is pleased with the system. He
placed a face mask paper filter on the intake of a small vacuum cleaner
(e.g. Dust Buster) for two minutes, in a room with approx. 3 picocuries
Radon per liter air. Next he placed the paper filter next to the RM-60's
Alpha-Beta window. This generated readings of several hundred
counts per minute. (Background count rate is normally about 10 CPM).
The software then drew a beautiful decay plot of the Radium B + C-C'
Radon daughters. The RM-70 and RM-80 would draw a decay curve with 10
and 24 times the data.
Others have found small amounts of radioactive contamination in drinking
water due to Radon, by simply placing the monitor next to a tank of
water and noticing the increase in reading. Floor drains, pipe
entrances, sump pumps, vent openings and more, all will become radioactive
if Radon is entering through and/or around them. The RM system allows
you to notice the effectiveness of remedial action.
Also real-time variations due to water flow, weather conditions, or
other variables are revealed on the graph and by way of the geiger
click rate and reading.
