Rad Term
This is the international unit of radioactivity.
What is the Becquerel?
Even the smallest exposure has some probability of causing a stochastic effect such as cancer; thus, the general philosophy is to maintain ALARA. ALARA is an acronym for this.
What is “As Low As Reasonably Achievable”?
Mouth pipetting this agent in high amounts can lead to jaw necrosis. Mouth pipetting is shown as a step in the purification process to be used by researchers such as Marie Curie and Henri Becquerel.
What is Radium?
This government agency is known for “Protecting People and the Environment” by regulating the use of byproduct, source, and special nuclear materials.
What is the Nuclear Regulatory Commission?
This Nuclear Power Plant accident that happened in March 1979 in Pennsylvania?
What is Three Mile Island accident?
The units for the quantity of energy absorbed from an exposure.
What is the rad or Gray?
This is the amount pregnant women can receive during their pregnancy when written notification to the Radiation Safety group occurs.
What is 0.5 rem or 500 mrem?
These workers used paint brushes to create fine details. Epidemiological studies later revealed many of these workers developed the disease of jaw necrosis.
Who are the radium watch dial painters?
This code of federal regulations concerns the transport of hazardous materials by any modality including radioactive material.
What is 49 CFR?
This nuclear power plant accident in April 1986 resulted in significant radiation doses to the thyroid gland from radioactive iodine and an increase in radiation induced thyroid cancers.
What is Chernobyl?
The determination of kinds, quantities, or concentrations of radioactive material in the human body by direct measurement (in vivo counting) or by evaluation of materials excreted (in vitro) from the human body uses this process.
What is a bioassay?
This is the dose limit that the general public should not exceed in any one hour.
What is 2 mrem in a hour?
This radiation type is only dangerous when emitted inside the body.
What is the alpha particle?
This code of federal regulations and part concerns the use of radioactive material in the healing arts. Or in Texas, this is the regulation.
What is 10 CFR Part 35?
What is 25 TAC §289.256 for Texas?
This disaster included a series of equipment failures, nuclear meltdowns, and releases of radioactive materials after the earthquake and tsunami on March 11, 2011 in Japan.
What is the Fukushima Daiichi nuclear disaster?
A reaction in which at least one heavier, more-stable nucleus is produced by combination of two lighter, less-stable nuclei. Reactions of this type release enormous amounts of energy.
What is the fusion reaction?
Alpha particles can be stopped by a single sheet of paper, beta particles can be absorbed by a few millimeters of aluminum, and gamma particles require this common type of material.
What is lead?
This type of effect is associated with long-term, low-level (chronic) exposure.
What is a stochastic effect?
The “radura” symbol shown here is internationally recognized as an indication of this and is displayed on products that are for sale to the public.
What is irradiated food?
An employer must maintain a record of all radiation accidents that could affect the environment and provide the records to this protection agency.
What is the Environmental Protection Agency (EPA)?
It consists of a gas-filled tube containing electrodes, between which there is an electrical voltage, but no current flowing. When ionizing radiation passes through and ionizes the gas within the tube a short, intense pulse of current passes from the negative electrode to the positive electrode and is measured or counted.
What is the Geiger-Mueller Counter?
This U.S. group has developed numerous recommendations regarding occupational average exposures for the U.S. population.
Who is the National Council on Radiation Protection & Measurements (NCRP)?
The factor by which the absorbed dose must be multiplied to obtain a quantity that expresses the biological damage to the exposed tissue on a common scale for all ionizing radiation.
What is the quality factor?
This is the year of the most Current Notice to Employees for general radioactive material use in Texas.
What is 2011?
In May of 2019, a sealed source recovery led to extensive Cesium contamination. Where did this occur?
What is Seattle, Washington?
