Fluke's Bleeper mR - Personal Radiation Monitor. |
INTRODUCTION: The slim, compact Bleeper mR is the ideal personal monitoring device for alerting personnel to the presence of radiation in medical, industrial or research settings. It accurately measures and displays the radiation dose received. APPLICATIONS: The only control is a switch to turn off and reset the instrument, making Bleeper mR extremely easy to use. For added safety, the switch is recessed. An easy-to-read LCD Display provides a continuous indication of accumulated dose. The loud "BLEEP" sounds every 15-30 minutes on background and becomes more frequent as dose rate increases, becoming a continuous sound in high radiation fields. A series of quiet "clicks" indicates it is properly functioning. Bleeper mR is an enhanced version of the highly popular Bleeper III and utilizes the same proven technology. SPECIFICATIONS: |
Bleep rates for background radiation: Approx. 1 bleep every 15-30 minutes.
1 mR/h: approx. 1 bleep every 20 seconds.
Energy Range: 45 keV to 6 MeV (±25%)100 mR/h and above: continuous signal to at least 60 Sv/h (6000 R/h) Dose rate response: Linear to 5 R/h (±20%) Display: LCD 0.1 mR to 999,999.9 mR Battery: Three alkaline batteries, size AAA. Typical battery life is 1 year. Temp. Range: -4°F to + 122°F (-20°C to + 50°C) Dimensions: 1.4(w) x 6"(d) (3.56 x 15.24 cm) Display area: 0.6 x 0.9" (1.52 x 2.29 cm) Weight: 0.25 lb (0.11 kg) |
Fluke's Bleeper III - Personal Radiation Monitor. |
Here is a simple, convenient instrument for alerting personnel to the presence of ionizing radiation. It provides a clear, audible indication of gamma and x-ray dose rates. No controls or adjustments are required. The instrument operates continuously, giving a bleep every 15 minutes for normal background radiation, increasing with the dose rate to a continuous tone when high radiation doses are present. This compact unit slips easily into the pocket, where it is firmly held by a clip. |

Fluke's Direct Reading, Pocket Dosimeters. |
Available in a wide selection of ranges, to meet all of your
requirements.
Direct-Reading Pocket Dosimeters from Nuclear Associates are rugged, precision instruments designed specifically for measuring accumulated quantities of gamma and x radiation. In use, the dosimeter is normally clipped to a pocket or to the outside of a lead apron. By checking the dosimeter reading periodically, the wearer is able to determine the exposure received during specific procedures. By knowing where and when greater-than-normal exposures occur, the wearer can identify the source and take quick, corrective action. Nuclear Associates currently offers five dosimeters. Each dosimeter has a color-coded clip that signifies its range. This will help the user to identify the dosimeter (i.e. black clip= 0-200 mR, blue clip= 0-5R, etc.), and ensure that the intended dosimeter is utilized. Nuclear Associates' Direct-Reading Pocket Dosimeters are extremely easy-to-use. To read the integrated exposure, the user looks through the dosimeter eye-piece while pointing the unit toward any external light source. The exposure is determined by the position of a hairline fiber against a graduated scale. A dosimeter Charger (model 06-912) is used to re-zero the dosimeter. The 0-200 mR Low-Energy Dosimeter is the most popular type for measuring personal radiation doses in hospital |
applications including fluoroscopy, portable radiography and angiography. Our high-energy dosimeters are ideal for
nuclear medicine and health physics applications. All direct-Reading Pocket Dosimeters are hermetically-sealed using
state-of-the-art plastics and epoxy resins. These reliable, high-quality devices meet ANSI specifications N13.5 and
N322, as well as military requirements. SPECIFICATIONS:

Clip: Glass fiber-filled, high-strength plastic Dimensions: Length: 4.5 (12.4 cm); Diameter: 0.6 (1.5cm) Weight: 1.0 oz (25 grams) |
Combo Dosimeter Charger and Storage Case Kit:
Nuclear Associates' standard Dosimeter Charger (model 06-912) comes in a rugged leatherette-covered case that holds up
to 12 dosimeters. A chart conveniently affixed inside the case permits quick identification of each dosimeter and its
user. The charger can be easily removed for battery change.
SPECIFICATIONS:
Dimensions: 9-1/2" L x 5-1/4" W x 5" H
Weight: 5 lbs Dosimeter Charger:
For zeroing all direct-reading dosimeters. This transistorized unit has a power supply that "zeroes" all direct-reading
dosimeters. One standard 1.5V "D" cell permits thousands of operations. A safety spring in the charging socket prevents
damage from excessive pressure on the dosimeter. Protective cap keeps the socket free of dust and moisture when not in
use. 4" x 4" x 3" high (l0cm x 10cm x 7.6cm) 2 lbs. |
