Clinical Radiation Dosage

The British Journal of Radiology, 1949
A clinical unit of radiation dosage (the rec or rontgen equivalent clinical) based on the rontgen under standard treatment conditions, is described. The relative biological effects of specific ion-density, over-all time, and field size are calculated so that equivalent dosage can be obtained under all treatment conditions.

Radiation dosage associated with ball lightning [PDF]

open access: possibleNature, 1974
A BALL lightning event occurred in a house in North Berkshire on May 8, 1970; here we report subsequent investigations using thermoluminescent dating techniques. According to some theories1–4 matter close to the path of such an event may experience a radiation dose of order 1 to 1,000 rad.

Thermoluminescence, low radiation dosage and black-body radiation [PDF]

open access: possiblePhysics in Medicine & Biology, 1967
It is shown that the emission of quanta in the visible region by the heating unit of a thermoluminescence reader is a major source of spurious signal in observations of low radiation dosage. At a heater temperature of 300 degrees C, about 120 photoelectrons per second are emitted from an S11 photomultiplier cathode for a typical reader construction.

Diacetylenes as radiation dosage indicators

Radiation Physics and Chemistry (1977), 1981
Abstract It is shown that diacetylenes, RCCCCR are highly sensitive gamma ray dosage indicators. When exposed to high energy radiation, diacetylenes first partially polymerize to a blue or red color. The color intensifies with increasing dosage and finally, they undergo a color transition, blue (or red)-to-metallic.
