Sodium iodide (NaI) is a white, crystalline chemical compound composed of sodium and iodine atoms. It is the salt of hydriodic acid and calcined soda. Sodium iodide has many applications in various fields, including medicine, photographic industry, and nuclear industry.

In the photographic industry, sodium iodide is used as one of the components in photosensitive emulsions. It is an important ingredient in the production of photographic plates and films.

In science and the nuclear industry, sodium iodide is used as a scintillator in gamma and beta radiation detectors. Scintillators are substances that react to ionizing radiation, generating visible or near-infrared light that can be detected by measuring devices.

How does sodium iodide work? 

Sodium iodide works by delivering iodine to the body, which is essential for the production of thyroid hormones. After sodium iodide is consumed, this chemical compound is absorbed from the gastrointestinal tract and transported to the thyroid gland.

In the thyroid gland, sodium iodide is converted into molecular iodine, which is then combined with tyrosine amino acids to form thyroid hormones – thyroxine (T4) and triiodothyronine (T3). These hormones control many metabolic processes in the body, including the rate of metabolism, brain and nerve development, as well as the functioning of the cardiovascular system.

Sodium iodide can also act as an antiparasitic agent, as iodine is toxic to certain types of parasites such as bacteria, fungi, and protozoa. In cases of parasitic infections, sodium iodide can be used as an adjunctive therapeutic agent in combination with other medications.

Sodium iodide used in the photographic industry

Sodium iodide is used in the production of photographic plates and films as one of the components in photosensitive emulsions. These emulsions consist of a gelatin base that contains silver halides (e.g., silver chloride) and a chemical compound, which can include sodium iodide. During the production process of photographic plates and films, the photosensitive emulsion is applied to a substrate (e.g., transparent film) and then subjected to the developing process. This process involves exposing the plate or film to light, which triggers a chemical reaction in the emulsion, resulting in positive and negative images. Sodium iodide plays an important role here as it introduces halides into the emulsion, allowing the capture of images with different sharpness and contrast.

Sodium iodide in the nuclear industry

Sodium iodide has several applications in the nuclear industry, where it is primarily used as a component of radiation control agents and as a substrate in the production of nuclear fuel.

One of the main uses of sodium iodide in the nuclear industry is the production of scintillators, which are used for detecting ionizing radiation in radiation detectors. Scintillators typically contain a crystalline chemical compound that emits visible or ultraviolet light upon exposure to radiation. Sodium iodides, such as NaI(Tl), are popular components of scintillators because they have the ability to produce highly intense scintillation light in response to radiation.
