One thousand volts.

Distribution lines in residential areas usually are 12 kilovolts (12,000 volts).

The highest kilovoltage used in producing a radiograph.

A unit of energy commonly used in nuclear and particle physics, equal to the energy acquired by an electron in falling through a potential of 1,000,000 volts.

A unit of radioactive power, equal to the power generated by one curie emitting an average energy of 10⁶ electronvolts per disintegration.

A unit of electricity equivalent to one million volts.

In radiation therapy, voltage greater than one megavolt.

A unit of electricity equivalent to one thousandth of a volt.

A unit of electric potential equal to one billionth of a volt.

An "electric potential" refers to the work required to bring a unit of positive electric charge from infinity to a specific point in an electric field or the amount of work needed to move a unit electric charge from a reference point to a specific point against an electric field.

The voltage, applied across the electrodes in the detecting chamber of a radiation detection instrument, that enables the detection of an ionizing event.

1. High voltage, as used for x-ray production, in the range of 200 to 300 kilovolts.
2. The medium-voltage radiation energy used in the treatment of cancer.
3. In radiation therapy, voltage in the range of 140 to 400 kilovolts, as contrasted to supervoltage (voltage between 500 kilovolts and one megavolt) and megavoltage (voltage greater than one megavolt).

The maximal electric potential of a pulsating supply or of an alternating supply during the half-cycle in which flow of current occurs.

The percentage of the total available light captured by plants that is subsequently converted into chemical energy.

1. Employing the photoelectric effect; that is, the production of electric power from electromagnetic radiation.
2. Relating to, or designating devices that absorb solar energy and transform it directly into electricity.
3. Able to generate a current or voltage when exposed to visible light or other electromagnetic radiation.

A single semiconducting element of small size (for example, one square centimeter) that absorbs light or other bands of the electronmagnetic spectrum and emits electricity.

A solid-state device that converts light directly into electricity, with voltage-current characteristics that are a function of th characteristics that are a function of the characteristics of the light source and the design and materials of the device.

These devices are made of various semiconductor materials including silicon, cadmium sulfide, cadmium telluride, and gallium arsenide, in single crystalline, polycrystalline, or amorphous forms.
