Pocket Dosimeter
Pocket Dosimeter
US$145.
Arrow-Tech  Pocket Dosimeters are rugged, precision instruments about the size of a pocket fountain pen, which are used to measure accumulative doses or quantities of gamma & X-ray  radiation. A metal clip is used to attach the dosimeter to an individual's pocket or to any available object in an area to be monitored for total radiation exposure.  It is pocket-size, conductive-fiber electroscope with an ion chamber for detecting and indication integrated exposure to gamma and x-radiation. It has a thin wall which permits the penetration and detection of radiation.

Reset any quantity of Pocket Dosimeters with a simple, dependable battery powered Dosimeter Charger after use.  See specifications below.

The way to "read" a Pocket Dosimeter is to just point it at a light source so that you can look through it and see the scale.  The conductive fiber  moves across a very clear well marked scale that produces the reading. 
.
Pocket Dosimeters use an extremely sensitive fiber electrometer type voltmeter and a small volume of air to measure the total amount of radiation to which the instrument has been exposed. A reading may be made at any time by merely looking at a source of light through the eyepiece end of the instrument.  The reading here is at zero.  The particular dosimeter shown is the 200mR model. 
.
A Pocket Dosimeter can be worn like a pen in your pocket or clipped to a belt.  It can be set outside for an hour, to tell the radiation rate.  You don't have to have a radiation meter if you have a dosimeter and are not in a hurry to measure the rate.
.
Dosimeters include an extra hard synthetic sapphire window to protect the lens even in the toughest of conditions. 

Units shown are rem (R), milli-rem (mR), and milli-Sievert (mSv).  A rem (R) is Roentgen Equivalent in Man, the ionizing radiation biologically equivalent to one typical high-penetration x-ray.  A Sievert (Sv) is an international unit,  1Sv equals 100R

A milli-rem (mR) is 1/1000th R.  A  milli-Sievert (mSv) is 1/1000th Sv.  1mSv = 100mR
A micro-Sievert (µSv) is 1/1000000th (Millionth) Sv.   1µSv = 0.1 mR

See Wikipedia for additional information.
.
Reset any Pocket Dosimeters with the Dosimeter Charger, available separately.  A single charger can reset a great many dosimeters over and again. 

Rate of Exposure can be calculated with any model.  Reset dosimeter, then take a six minute reading; that amount x10 is mR/hr.  (Pocket 2 recommended)

Pocket Dosimeter model 2 is ultra sensitive to normal background radiation, max reading is accumulated within a 24-hour period in any normal environment.  Excellent for use in calculating Rate of Exposure.  Otherwise, for use in special applications only.  Price us$210.00 each.
