PRM-8000 or PRM-9000 What Is the Difference?
The PRM-9000 is 3.5 times more sensitive to nuclear radiation, but cannot be taken
outside above 10,000 feet without risking damaging the Geiger tube - rendering the
device inoperative. Flying or shipment by commercial air is fine. The PRM-8000 is lighter
and more rugged. The PRM-9000 is best for detecting lower levels of contamination in
items quickly. The PRM-8000 is also able to detect lower levels of contamination in
items, but requires more time (using the timed measurement functions). No Geiger
counter is exceptional for detecting trace contamination in food, but the PRM-9000,
with its pancake tube is the better of the two for scanning food.

Over two years in development, the CE-compliant PRM-8000 Geiger Counter is released to the market at a time when many people and organizations are making the detection, measurement and monitoring of nuclear radiation a high priority. This Geiger counter delivers laboratory grade performance in a small package. Battery life is over 6-years under normal conditions from a single, readily-available, 9-volt lithium battery that is user-installable without soldering. (Standard alkaline 9-volt batteries available virtually everywhere provide over 3-years of life under normal conditions.) We know of no other nuclear radiation monitor anywhere that can provide this level of battery life from standard, user-replaceable batteries without soldering.
The two-line, alphanumeric display supports both English and Japanese languages promoting ease-of-use and concise measurement. The display is backlit to support low-light conditions. The Geiger counter's unique Radiation Monitoring Engine (RME) is always-on collecting measurements enabling rapid environment assessment.
Using only one key, users can scroll through several screens that display present, average, maximum and minimum measurements in uR/hr, mR/hr, uSv/hr, Counts per Second (CPS) or Counts per Minute (CPM). The PRM-8000 instrument not only records the maximum radiation measured, but also displays the time and date at which the maximum occurred.
With over 100K bytes of data logging memory included, this Geiger Counter can autonomously store up to 91,466 minutes or hours of time-stamped measurements. These measurements can then be uploaded to a PC in CSV format for analysis. A user-settable dose rate alarm sounds an audible alert when the measured radiation level exceeds that of the alarm level setting.
Designed by Mazur Instruments and manufactured in the USA, the PRM-8000 Geiger counter includes abundant I/O options including support for headphones, external speakers, external power and USB data exchange (USB cable not included).
Scan items for radiation, detect Naturally Occurring Radioactive Materials (NORM) and continuously monitor your environment. The PRM-8000 is an ideal solution for First Responders, Homeland Security, Medical Safety, Educators, Researchers and Geologists.

Minimum energy sensitivity alpha (2.5 MeV), beta (50 keV), gamma/X rays (10 keV). Gamma sensitivity: 1,000 CPM/mR/hr (Cs-137).
Comparison to the Soeks Geiger Counter
The Soeks unit relies on rechargeable batteries and the battery life is considerably less than our PRM units - only 10 hours before recharge. Compare the constant monitoring battery life of the PRM-9000 at 2.33 years or the PRM-8000 at 3.2 years!
The Soeks unit is smaller and has a larger display, but the small size requires small batteries and the color display takes more power. Combined, this results in poor battery life and the requirement to have AC power readily available 24/7 for any long term monitoring.
However, a crtical draw back of this unit is that it only detects gamma radiation and not alpha and beta. While they do not provide specifics on their detector, the pancake detector of the PRM-9000 is far superior in sensitivity. The detector in the PRM-8000 is far superior as well.

Why Own a Geiger Counter?
The links in the text below provide independent background information on the topic
as heard on National Radio:
“Mazur said he developed handheld Geiger counters so consumers and hobbyists could be aware of radiation levels in the things around them. If you don't have some sort of instrument... you're completely a hundred percent certain that you have no idea what's in your environment," he cautioned. Mazur shared a report about elevator buttons in France that were made from recycled metal containing nuclear waste, as well as a story about radioactive metal tissue boxes sold by a major home good chain. A week spent near one of these 'hot' tissue boxes was equivalent to getting a chest x-ray, he revealed.”
With a Mazur Instruments PRM-8000 or PRM-9000 You Can:
- Check granite countertops, water filters, air filters, building materials and other items in your home for radioactive contamination
- Check for radioactivity in antiques, watch and clock dials, antique pottery, smoke detector, lantern mantels, etc.
- Monitor and maintain awareness amidst a nuclear accident or emergency
- Test for radioactive contamination of food
- Check for radioactivity in metal objects in your home or office that could be made of recycled radioactive materials
- Check for leaks or possible exposure if you work in or near an X-ray lab in a medical facility or medical office suite
- Check for environmental levels of radioactivity near a nuclear power facility
- Test the soil and environment for dangerous levels of radioactivity, if are in close proximity to uranium mines
- Monitor personal levels of radiation due to radiation therapy, brachytherapy or other medical procedures that rely
on radioactive  substances

About Geiger Counters
Nuclear radiation is a normal part of our planet and the cosmos. It is also a by-product of man-made actions and activities. The unfortunate catastrophe in Japan has created a new sense of urgency for personal radiation measurement to an entirely new generation of post-Cold War individuals.
Against this backdrop we will provide a fundamental description of how a Geiger counter detects nuclear radiation. First a few words on radiation, and a particular type called ionizing radiation.
Radiation is all around us. The sun radiates energy, radio stations radiate electromagnetic waves and radiators in apartment buildings radiate heat to keep residents warm in cold weather. However, nuclear radiation is a different type of radiation known as ionizing radiation.
Ionizing radiation alters the structure and, by association, the electric charge of individual atoms by a process known as ionization. The substances that produce ionizing radiation are said to be radioactive.
There are four types of ionizing radiation – alpha, beta and gamma radiation as well as x-radiation
(x-rays).
Generally, an alpha particle can travel no more than one to three inches in the air before stopping, and can be stopped by a piece of paper. However, they can pass through a thin mica window. As we will see later, this property of mica is very important in radiation measurement.
Beta radiation can pass through a sheet of paper and some clothing, but not through thin metal or glass. Beta particles can damage skin, however, both alpha and beta radiation are most harmful when inhaled or ingested.
Gamma radiation occurs naturally in nature and is almost identical to x-rays. Generally, they can travel into and often times through anything. Gamma particles can be shielded with several feet of water or concrete, several inches of steel, or a smaller amount of lead.
X-radiation is man-made radiation with a number of valuable uses in medicine and dentistry. X-rays are electromagnetic radiation of the same nature as light and radio waves, but they are also ionizing. They can penetrate a variety of materials, including body tissue. The shielding techniques for x-rays are similar to those for gamma radiation. This is why the x-ray technician will wear a lead apron when taking x-rays.
Having discussed the nature of radiation and the four primary types of ionizing radiation, we will now move to discussing how a Geiger counter operates.
The key element within a Geiger counter is a Geiger tube that consists of two electrodes separated by a mixture of gases. High voltage is applied to the electrodes which creates an electrical field within the chamber.
When radiation passes through the chamber and ionizes the gas, a pulse of electrical current is generated. This detection will typically result in a flashing of an LED and sounding of a “beep” on most Geiger counters. The pulses are electronically processed by the instrument and the radiation level measurement is displayed. The mica window on the tube allows alpha particles to pass so that they can be detected.
Some Geiger tubes only detect beta and gamma radiation leaving users blind to the presence of alpha particles.
Detecting alpha radiation is very critical because as radioactive substances decay they oftentimes decay into elements that produce alpha radiation. If these elements find their way into the food supply, individuals risk consuming food that contain alpha particles.
This is one of the key reasons that, at present, demand for high-quality, US-made, alpha-detecting Geiger counters is at record levels in Japan.
