➤ ²⁴¹₉₅Am (isotope of americium-241) - 59.57 keV.

➤ It has been used in therapeutic examinations and research in the field of magnetic resonance imaging and in the radiological diagnosis of the thyroid gland: under the influence of ɣ-rays, iodine in the gland begins to emit X-rays, the intensity of which depends on the concentration of iodine.

➤ Toxic effects are characterized by the development of radiation sickness, problems with the central nervous system and damage to the integrity of visceral organs.

➤ Antidote: Symptomatic therapy.

➤ In 1945, americium and curium were separated by ion exchange chromatography. Am⁺⁵ capable of disproportionation (Am⁺⁵ →Am⁺³ →Am⁺⁴).
